21C: Health and Safety in the medical use of ionising and non-
ionising radiation technologies.
P5: Explain the health and safety risks, side effects and limitations of non-ionising
and ionising radiation technologies.
Non-ionizing radiation, such as radio waves, microwaves, and visible light, have low energy and are
considered safe. However, prolonged exposure to intense non-ionizing radiation, such as from UV
rays, can cause skin damage and increase the risk of skin cancer. Ionizing radiation, such as X-rays and
gamma rays, have high energy and can damage DNA, leading to an increased risk of cancer. Exposure
to ionizing radiation should be minimized and carefully monitored. There are also limits to the
amount of radiation that people can be exposed to, which are set by regulatory agencies.

monitored. There are also limits to the amount of radiation that people can be exposed to, which are
set by regulatory agencies.
In addition to the risk of cancer, exposure to ionizing radiation can also cause radiation sickness,
which can lead to nausea, vomiting, and fatigue. In severe cases, it can cause organ failure and death.
There are also risks associated with the use of radiation in medical procedures, such as X-rays and CT
scans. While these procedures can be extremely helpful in diagnosing and treating medical
conditions, they do expose patients to ionizing radiation. The risk of harm from these procedures is
low, but it is important to carefully consider the benefits and risks of any medical procedure.
Overall, it is important to minimize exposure to both non-ionizing and ionizing radiation. This can be
done by limiting exposure to sources of radiation, such as the sun and X-rays, and by following safety
guidelines when working with sources of radiation, such as in medical facilities or nuclear power
plants.
Side effects
The side effects of non-ionizing radiation are minimal. However, prolonged exposure to intense non-
ionizing radiation, such as from UV rays, can cause skin damage and increase the risk of skin cancer.
The side effects of ionizing radiation exposure can be more severe. Exposure to ionizing radiation can
cause radiation sickness, which can lead to nausea, vomiting, and fatigue. In severe cases, it can
cause organ failure and death. Exposure to ionizing radiation can also cause DNA damage, leading to
an increased risk of cancer.
There are also side effects associated with the use of radiation in medical procedures, such as X-rays
and CT scans. While these procedures can be helpful in diagnosing and treating medical conditions,
they do expose patients to ionizing radiation. The side effects of these procedures are low, but they
can include skin redness, hair loss, and an increased risk of cancer. It is important to carefully
consider the benefits and risks of any medical procedure that involves radiation. In some cases, the
, benefits of the procedure may outweigh the risks. However, in other cases, alternative procedures
that do not involve radiation may be a better option.
Overall, it is important to minimize exposure to both non-ionizing and ionizing radiation to reduce
the risk of side effects. This can be done by limiting exposure to sources of radiation, such as the sun
and X-rays, and by following safety guidelines when working with sources of radiation, such as in
medical facilities or nuclear power plants.
Limitations
There are some limitations to the use of radiation in medical procedures. While X-rays and CT scans
can be helpful in diagnosing and treating medical conditions, they do expose patients to ionizing
radiation. The risk of harm from these procedures is low, but it is important to carefully consider the
benefits and risks of any medical procedure.
There are also limitations to the amount of radiation that people can be exposed to, which are set by
regulatory agencies. These limits are designed to minimize the risk of harm from exposure to
radiation. In addition, there are limitations to the effectiveness of radiation therapy in treating
cancer. While radiation therapy can be highly effective in killing cancer cells, it can also damage
healthy cells and tissues. This can lead to side effects such as fatigue, skin irritation, and hair loss. In
some cases, radiation therapy may not be effective in treating certain types of cancer.
Overall, while radiation can be a powerful tool in diagnosing and treating medical conditions, there
are limitations to its use. It is important to carefully consider the benefits and risks of any medical
procedure that involves radiation, and to follow safety guidelines to minimize the risk of harm from
exposure to radiation.
Safety precautions, side effects & risks for operators/patients of non-
ionising radiation
Non-ionizing radiation is a type of radiation that does not have enough energy to ionize atoms or
molecules. Examples of non-ionizing radiation include radio waves, microwaves, infrared radiation,
visible light, and ultraviolet radiation.
While non-ionizing radiation is considered to be safe, there are still safety precautions that should be
taken to minimize the risk of harm to both operators and patients. For operators of equipment that
emits non-ionizing radiation, such as microwave ovens or radio transmitters, it is important to follow
safety guidelines to minimize the risk of harm. This can include wearing protective clothing or
equipment, such as gloves or goggles, to reduce the risk of skin or eye damage. Operators should
also be trained in safe handling procedures and should be aware of the potential risks associated
with exposure to non-ionizing radiation. For patients who are exposed to non-ionizing radiation
during medical procedures, such as ultraviolet radiation during phototherapy or infrared radiation
during laser surgery, there are also safety precautions that should be taken.
Patients should be informed of the potential risks associated with exposure to non-ionizing radiation
and should be given the opportunity to ask questions and voice any concerns they may have. In
addition to safety precautions, it is also important to be aware of the potential side effects and risks
associated with exposure to non-ionizing radiation. While the side effects of non-ionizing radiation
are minimal, prolonged exposure to intense non-ionizing radiation, such as from UV rays, can cause
skin damage and increase the risk of skin cancer.
There are also some risks associated with the use of non-ionizing radiation in medical procedures.
For example, exposure to infrared radiation during laser surgery can cause burns or tissue damage,
