Occupational exposure to radiation

... considers different sources and types of radiation that may occur in the workplace and how these are controlled.


Exposure to ionizing radiation occurs in many occupations. Artificial sources of radiation are commonly used in the manufacturing and service industries, in areas of defence, in research institutions, and in universities, as well as in the nuclear power industry. Moreover, we have seen in Chapter 8 that they are extensively used by physicians and health professionals.

Some workers are also exposed to natural sources of radiation in such circumstances that a measure of supervision and protection is required.

This is particularly true of exposure to radon in mines and in ordinary
premises throughout areas where radon levels are high.

With the relatively high dose rates experienced in air travel due to elevated levels of cosmic rays at flying altitudes, some consider that supervision is also required for air crew, although it is less clear to what extent their exposures can readily be reduced.
