There are many types of assignments given to students like individual assignments, group-based assignments, reports, case studies, final year projects, skills demonstrations, learner records, and other solutions given by us. We also provide Group Project Presentations for Irish students.

In this section, we are describing some activities. These are:

Assignment Activity 1: Provide a theoretical and practical basis for radiation safety workers to meet legal requirements.

The legal requirements for radiation safety workers in Ireland are based on the Ionising Radiations Regulations (S.I. No. 543 of 2011). These regulations require radiation safety workers to hold an appropriate authorization, which is issued by the Minister for Jobs, Enterprise, and Innovation.

The purpose of the regulations is to ensure that any person who may be occupationally exposed to ionizing radiation does not receive a dose of radiation that would exceed the dose limit specified in the regulations. In addition, the regulations also require employers to provide a safe working environment for their employees and to ensure that all necessary training is provided so that employees can safely carry out their duties.

Assignment Activity 2: Understand the following subject areas in a general context:

Units of radiation exposure and dose.

The SI unit of radiation exposure is the gray (Gy), and the SI unit of radiation dose is the sievert (Sv). One Gy corresponds to 1 J/kg, and one Sv corresponds to 1 W/kg.

1 Gy = 1 J/kg = 100 rad

1 Sv = 1 W/kg = 1000 rem

Radiation protection quantity is used to express the biological effect of low levels of ionizing radiation on the human body.

The sievert is the radiation protection quantity used to express the biological effect of low levels of ionizing radiation on the human body. The sievert takes into account the different sensitivities of different tissues and organs to radiation and is, therefore, a more accurate measure of the health risk posed by ionizing radiation than the gray.

The sievert is also used to express the dose equivalent, which is the product of the absorbed dose and a weighting factor that takes into account the different sensitivities of different tissues and organs to radiation. The unit of dose equivalent is the sievert per unit of exposed area (Sv/m2).

The effective dose is the product of the absorbed dose and a weighting factor that takes into account the different sensitivities of different tissues and organs to radiation. The unit of effective dose is the sievert (Sv).

The maximum permissible dose (MPD) is the dose of ionizing radiation that a person may receive in their lifetime without undue risk to health. The MPD is set by each country’s regulatory authorities.

The annual limit on intake (ALI) is the maximum permissible amount of a given radionuclide that can be ingested or inhaled in one year by an adult worker without exceeding the MPD.

The derived air concentration (DAC) is the maximum permissible concentration of a given airborne radionuclide in workplaces that would result in an intake by an adult worker of no more than the ALI for that radionuclide.

The permissible dose (PD) is the maximum dose of ionizing radiation that can be received by a member of the public without undue risk to health. The PD is set by each country’s regulatory authorities.

Biological effects of ionizing radiation.

Ionizing radiation is a source of energy that can cause chemical changes in molecules, including DNA. This type of radiation has enough energy to remove an electron from an atom, which is how it ionizes or electrifies the atom. When ionizing radiation passes through tissue, it can damage the cells and tissues it comes into contact with.

The severity of the damage depends on several factors, including the type and amount of radiation exposure, as well as the age and health of the person exposed. Cells that are actively dividing are more vulnerable to radiation-induced damage than those that are not dividing. The effects of ionizing radiation can range from mild (such as skin reddening) to severe (such as cancer or death).

The primary health risks associated with ionizing radiation exposure are cancer and genetic damage. Exposure to ionizing radiation can increase the risk of developing cancer, and the risk is proportional to the dose received. In other words, the higher the dose, the greater the risk.

Radiation detection and measurement.

Radiation detection and measurement is the process of detecting and measuring radiation.

There are a variety of different methods for detecting radiation, including Geiger counters, scintillation counters, proportional counters, and ion chambers. Each of these detection methods has its own strengths and weaknesses.

Radiation measurements can be expressed in a variety of different units, including millirem, rem, sievert, and becquerel. The unit used will depend on the type of radiation being measured and the context in which it is being used.

Irish legal issues and international framework in radiation safety.

Ireland has a well-developed legal system that is based on English common law. The Irish court system is made up of the Supreme Court, the Court of Appeal, and the High Court. In addition, there are specialist courts including the Commercial Court and the Bankruptcy Court.

The main legislation in relation to radiation safety is the Radiological Protection Act 2005. This Act sets out principles for protecting people and the environment from ionizing radiation. It also establishes An Garda Síochána (Irish police) as the competent authority for implementing radiography safety regulations. Under this Act, persons carrying out certain types of work with ionizing radiation must be registered with An Garda Síochána and comply with specific safety requirements.

The Radiological Protection Institute of Ireland (RPII) is the radiation protection authority in Ireland. The RPII is responsible for providing advice on all aspects of ionizing radiation, including its health effects, environmental impact, and safe use.

Ireland is a member of the International Atomic Energy Agency (IAEA), and as such, it is subject to the IAEA’s radiation safety standards. These standards are implemented in Ireland through the Radiological Protection Act 2005 and the Radiological Protection Regulations 2006.

Assessment of internal and external exposures.

When assessing the risks associated with ionizing radiation exposure, it is important to consider both the internal and external exposures.

Internal exposure occurs when radioactive material enters the body through inhalation, ingestion, or absorption through the skin. This type of exposure is of particular concern because radioactive material that is inside the body can be difficult to remove and may continue to expose the individual to radiation for a long period of time.

External exposure occurs when an individual is exposed to ionizing radiation from sources outside the body, such as X-rays or radioactive fallout. This type of exposure is less of a concern because the radioactive material is not inside the body and can be more easily removed.

The assessment of internal and external exposures is important because the risks associated with ionizing radiation exposure are different depending on the type of exposure.

Protection against occupational exposure.

There are a number of different ways to protect workers from occupational exposure to ionizing radiation.

One way is to use engineering controls, such as lead shielding, to minimize the amount of radiation that workers are exposed to.

Another way is to use work practice controls, such as keeping radioactive material away from areas where workers are present.

Finally, personal protective equipment, such as lead aprons, can be used to protect workers from exposure to ionizing radiation.

The type of control that is used will depend on the specific circumstances of the workplace and the type of work that is being done.

Emergency planning.

In the event of a radiation emergency, it is important to have a plan in place to protect people and property from exposure to ionizing radiation.

The first step is to evacuate people from the area that is affected by the radiation.

Once people have been evacuated, it is important to decontaminate them to remove any radioactive material that may be on their bodies.

Finally, it is important to monitor the area for radiation levels and to take steps to reduce the level of radiation if necessary.

Non-ionizing radiation.

Non-ionizing radiation is electromagnetic radiation that does not have enough energy to ionize atoms. Examples of non-ionizing radiation include radio waves, microwaves, and visible light. Non-ionizing radiation is less harmful than ionizing radiation because it does not damage the DNA of cells.

However, non-ionizing radiation can still be harmful if it is intense enough or if it is absorbed by the body over a long period of time. The International Agency for Research on Cancer (IARC) has classified non-ionizing radiation as a possible human carcinogen. There are a number of ways to protect against exposure to non-ionizing radiation, including limiting exposure time, maintaining a distance from the source of radiation, and using shielding.

Assignment Activity 3: Establish the understanding from which they may develop practical expertise in radiation safety.

Radiation safety is the practice of protecting people and the environment from ionizing radiation. It includes reducing radiation hazards, monitoring radiation levels, and educating workers and the public about radiation safety.

Radiation hazards can arise from natural sources (such as cosmic rays and radon) or artificial sources (such as medical X-rays and nuclear power plants). Ionizing radiation can cause cancer and other health problems. To protect people and the environment, radiation safety practices include:

  • Controlling exposures to ionizing radiation
  • Monitoring workers’ exposures
  • Training workers in radiation safety procedures
  • Educating the public about radiation hazards

When working with ionizing radiation, it is important to take precautions to minimize the risk of exposure. These precautions include:

  • Keeping the source of radiation away from people
  • Using lead shielding to block the radiation
  • Wearing personal protective equipment, such as lead aprons
  • Monitoring the level of radiation in the area

Assignment Activity 4: Demonstrate their detailed professional knowledge from their own field and be required to debate and apply current research and practice into the wider professional arena in a multidisciplinary context.

Detailed professional knowledge is critical for success in any field. However, mere theoretical knowledge is not enough; one must also be able to debate and apply current research and practice to the wider professional context. This requires a deep understanding of the subject matter, as well as the ability to think critically and solve problems.

For example, in the field of medicine, doctors are required to have extensive knowledge of human anatomy and physiology, diseases, and treatments. They must be able to apply this knowledge in a clinical setting, making decisions based on the best available evidence. In addition, they must be able to communicate effectively with patients and their families, as well as other members of the healthcare team.

The same principles apply in other professions, such as law, engineering, and teaching. In each field, professionals must have detailed knowledge of the subject matter, as well as the ability to apply that knowledge in a real-world setting.

Assignment Activity 5: Critically evaluate radiation safety policies and procedures in their professional lives.

Radiation safety policies and procedures are designed to protect people and the environment from the harmful effects of ionizing radiation. However, these policies and procedures are not perfect, and there is always room for improvement.

It is important for professionals who work with ionizing radiation to critically evaluate the policies and procedures that are in place. This evaluation should consider the effectiveness of the policies and procedures, as well as the potential for improvement. In addition, professionals should be aware of the latest research on radiation safety, so that they can make informed decisions about how to best protect people and the environment.

Assignment Activity 6: Critically evaluate the radiation safety principles and their role within them.

There are four general principles of radiation safety: time, distance, shielding, and Homestead Berks material. These are basic tenets that should be followed in order to ensure safety when dealing with radioactive materials. Let’s explore each principle in more depth. 

The first principle is time. When working with radioactivity, it is important to limit exposure time as much as possible. The longer you are exposed to radiation, the greater the risk of developing health issues such as cancer. It is therefore important to work quickly and efficiently when handling radioactive materials, to minimize the amount of time spent in contact with them. 

The second principle is distance. It is important to maintain a safe distance from radioactive materials, in order to minimize exposure. The further away you are from a source of radiation, the less radiation you will be exposed to. It is therefore important to stay as far away from radioactive materials as possible and to use distance to your advantage when working with them. 

The third principle is shielding. Shielding is used to protect people and equipment from radiation. Lead is the most common material used for shielding, as it is highly effective at absorbing radiation. However, lead is also heavy and expensive, so it is not always practical to use lead shielding. Other materials, such as concrete, water, and even air, can also be used to shield against radiation. It is important to choose the right type of shielding for the job, to ensure that people and equipment are protected. 

The fourth and final principle is material. It is important to use materials that are not radioactive when working with radioactive materials. This helps to minimize the risk of contamination and exposure. Non-radioactive materials, such as plastic or glass, are often used in laboratories and other environments where radioactivity is present.

These are the four basic principles of radiation safety. By following these principles, professionals can help to ensure the safety of themselves, their colleagues, and the general public.

Assignment Activity 7: Consider the handling of multifaceted issues in which judgments are made whilst reflecting upon the wider professional issues and the responsibilities of their role as a professional within this area.

When making judgments about multifaceted issues, it’s important to consider the wider professional context and the responsibilities of those involved. For example, in the case of a healthcare worker who is asked to make a judgment about whether or not to provide life-saving treatment to a patient, they need to weigh up all of the relevant factors including the patient’s medical history and current condition, as well as their own ethical and moral beliefs.

Likewise, in the case of a social worker who is asked to make a judgment about whether or not to place a child into foster care, they need to weigh up all of the relevant factors including the child’s safety and well-being, as well as the capabilities and resources of potential foster parents.

Making judgments about multifaceted issues is never easy, but it’s important to consider all of the relevant factors and to act in the best interests of those involved.

Assignment Activity 8: Examine current issues in radiation safety and apply these to clinical/industrial decision-making and problem-solving processes.

There are a number of current issues in radiation safety that need to be considered in clinical and industrial settings. One key issue is the need to Balance conflicting objectives, which often means making decisions that involve trade-offs. For example, when choosing a course of treatment for a patient, medical professionals must consider the risks and benefits of using radiation. On one hand, they want to maximize the benefits by using the most effective dose possible; on the other hand, they want to minimize the risks by using the lowest possible dose.

Radiation protection must also be incorporated into decision-making processes at both individual and organizational levels. Unfortunately, human factors such as cognitive biases can lead people to make poor decisions about how to manage radiation risks. For example, the sunk cost fallacy can lead people to continue using a particular piece of equipment or material even if it is no longer the best option because they have already invested so much money in it.

Organizations also need to consider how to allocate resources efficiently in order to protect people from radiation risks. This often means making tough decisions about which risks are the most important to address and which can be managed with existing resources.

There are many current issues in radiation safety, but by considering these issues in decision-making and problem-solving processes, organizations and individuals can help to protect people from unnecessary risks.

Assignment Activity 9: Have the ability to critically reflect and evaluate their individual professional practice and knowledge base in order to recognize their need for continuous professional development and lifelong learning.

All professionals need to continuously reflect on and evaluate their practice in order to improve their skills and knowledge. This is especially important in the field of radiation safety, as the risks associated with exposure to radiation are constantly changing. For example, new research may reveal that a particular type of radiation is more harmful than previously thought, or that a certain type of equipment is not as effective at reducing exposure as previously thought.

Continuous reflection and evaluation also allow professionals to identify their own areas of weakness and to seek out additional training or education in order to address these weaknesses. For example, a radiation safety officer who is not well-versed in the latest research on radiation risks may need to take some courses or attend seminars in order to update their knowledge.

Continuous professional development and lifelong learning are essential for all professionals, but they are especially important in the field of radiation safety. By continuously reflecting on and evaluating their practice, radiation safety professionals can ensure that they are up-to-date on the latest information and that they are able to effectively protect people from radiation risks.

Assignment Activity 10: Demonstrate the ability to source and analyze relevant literature. This will be examined at the end of the semester.

When conducting research, it is important to be able to source and analyze relevant literature. This involves finding sources that are relevant to the topic of research and then critically evaluating the information in those sources.

There are a number of ways to find relevant sources of information. One way is to use search engines such as Google Scholar or PubMed. Another way is to use databases such as the Web of Science or Scopus. Once potential sources have been found, it is important to read them carefully and critically evaluate the information they contain.
