PPT-Radiation risks 2

Continued Minimising Exposure As any exposure to ionising radiation could potentially damage cells and lead to cancer w hen handling radioactive materials and in situations where workers are exposed to ionising radiation the ALARA principle should be employed. The US Environmental Protection Agency EPA is responsible for advising the government on radiation hazards and regulating certain sources of radioactivity in the environment This booklet provides basic facts about radiation science as well as inform of Mars.

What is radiology?. Radiology is a branch of medicine that uses imaging technology to diagnose and treat disease.. Radiology may be divided into two different areas, diagnostic radiology and interventional radiology. Doctors who specialize in radiology are called radiologists..

Radiation is the emission of energy in the form of waves or particles. Radiation that is so powerful that it can remove electrons from atoms is called ionizing.. Examples of types of ionizing radiation are x-rays from medical machines and gamma rays from radioactive substances. . •. Radiation biology . is the study of the action of ionizing radiation on living organisms . •The action is very complex, involving physics, chemistry, and biology . –Different types of ionizing radiation . Generally, work may not begin . until . an investigation and risk assessment have been conducted, as well as the necessary measures taken to prevent occupational health risks and accidents. .
