Ionizing radiation: overview [PDF]

Occupational Medicine, 2006
The role of the occupational physician is to provide advice to employers, in areas such as radiation health, health aspects of contingency planning as well as radiation health advice to the worker, both for routine and accidental exposures. These roles require awareness of radiation science and developments in the field.
