You asked: Why do we need radiation protection?

Why is protection from radiation needed?

Radiation protection is to prevent the occurrence of harmful deterministic effects and to reduce the probability of occurrence of stochastic effects (e.g. cancer and hereditary effects).

What is radiation and why is it important?

It is used in medicine to diagnose illnesses, and in high doses, to treat diseases such as cancer. Also, high doses of radiation are used to kill harmful bacteria in food and to extend the shelf life of fresh produce. Radiation produces heat that is used to generate electricity in nuclear power reactors.

What is meant by radiation protection?

Radiation protection, also known as radiological protection, is defined by the International Atomic Energy Agency (IAEA) as “The protection of people from harmful effects of exposure to ionizing radiation, and the means for achieving this”.

Why is radiation safety an important role in nuclear medicine?

The principles of the protection of workers from ionising radiation in all areas of medicine are directed at prevention of deterministic effects and minimization of risk for stochastic effects (cancer).

What are the advantages of radiation?

The advantages of radiation therapy include: death of a large proportion of cancer cells within the entire tumor (there are minimal, if any, cancer cells are left behind in small tumors; thus, radiation alone may be used to cure certain small tumors)

How is radiation used in healthcare?

Radiation is used in many medical imaging procedures. Medical imaging procedures deliver x-ray beams, a form of ionizing radiation, to a specific part of the body creating a digital image or film that shows the structures inside that area like bones, tissues, and organs.

How can we protect patients from radiation?

In general, alpha, beta, gamma and x-ray radiation can be stopped by:

  1. Keeping the time of exposure to a minimum,
  2. Maintaining distance from the source,
  3. When appropriate, placing a shield between yourself and the source, and.
  4. Protecting yourself against radioactive contamination by using proper protective clothing.

What is the concept of radiation protection in nuclear medicine?

The goal of radiation protection in nuclear medicine is to ensure that the expected medical outcome for the patient is achieved, and procedure optimized while limiting the radiation risk to the patients, medical personnel and public.

What are the three principles of radiation protection?

ALARA stands for “as low as reasonably achievable”. This principle means that even if it is a small dose, if receiving that dose has no direct benefit, you should try to avoid it. To do this, you can use three basic protective measures in radiation safety: time, distance, and shielding.

Why radiation protection is considered as an integral part of radiology department?

Because X-rays involve ionizing radiation that can deposit energy in human cells and cause tissue changes, it is important to minimize any associated risk to the patient. This is done by limiting the radiation exposure to the minimum required to create the clinical images needed to answer the medical question.
