This student manual included information regarding principles of nonionizing radiation and ionizing radiation, control of nonionizing and ionizing radiation, and instrumentation. This modularized course was intended for advanced training of students in the field of industrial hygiene with an emphasis on controlling exposures found in the workplace. The characteristics, sources, application, biological effects, and established threshold limit values for electromagnetic regions of the spectrum were considered, including ultraviolet, infrared, and radio frequency. The areas of microwaves and lasers were also considered. An overview was provided of management and control of nonionizing radiation, with specific attention given to ultraviolet radiation, lasers, and microwave radiation The atom, radioactivity, and the process of radioactive decay were considered. Five types of ionizing radiation were examined, including alpha, beta, gamma, X-rays, and neutron radiation. The basic biological effects of ionizing radiation, applications of ionizing radiation, and the established maximum permissible dose levels for the working environment were presented. The most commonly used radiation detectors were discussed, including ionization chambers, proportional counters, Geiger-Muller counters, scintillation detectors, photographic devices, and solid state and activation devices.
