Radiation Safety

Safety of Radiation - Benefit and Risk

Ionizing radiation produces ion pairs, radicals, primary, secondary, and tertiary chemical reactions. All these affect our health state. Thus, safety is an important issue in working with nuclear technology. Exposure to ionizing radiation should be avoided as much as possible.

Ionizing radiation damages living tissues and organisms. Its effect on life depends on the type of radiation, the rate at which the radiation is received, and dosages (amounts) of radiation received. The (tradional) cgs unit for dose is roentgen equivalent man (rem) whereas the SI unit for it is the sievert (1 Sv = 100 rem).

How much natural radiation do we receive each year? What doses are we receiving in a dental or chest examination? To make sense of answers these questions, we need to understand the quantities or dose units in radiation measurements.

Early Experience of Radiation Effects

Researchers and experimentalists usually take risks because they are highly interest in the subjects.

Early X-ray and uranium workers suffer dermatitis, skin lesions, lung cancers and other occupational diseases. The danger of radiatin exposure was realized soon after their discovery. There was a collective response to these risks.
