M. Nonchemical physical exposures in the workplace are important because they can cause systemic effects that mimic chemical toxidromes. The most important example is heat stress, which is a major occupational health issue. Other relevant nonchemioal, work-related physical exposure types include ionizing radiation, nonionizing radiation (such as ultraviolet, infrared, and microwave exposure), and increased barometric pressure (eg, among caisson workers). Except for extremes of exposure, the adverse effects of these physical factors are generally associated with chronic conditions. 

Physical hazards are concerned with items such as back injury, electrocution, rapid pressure change, and violence. Environmental hazards include items such as ionizing radiation, nonionizing radiation, building-related illness, and noise. 

Radiation. Exposure of persons or sensitive equipment to ionizing radiation, nonionizing radiation, ultraviolet or infrared hght, lasers, electromagnetic or radiofrequency emanations. Results can include bums to persons, stmctural damage to equipment, and initiating of ordnance devices.

We are constantly exposed to ionizing and nonionizing radiation from naturally occurring sources as well as radiation generated and managed by our society. The challenge is to understand and manage the risk and benefits of our individual exposure. 

Some radiation is helpful and necessary, as in the case of sunlight, which allows us to see the world. The nonionizing radiation of the sun warms us, but too much ultraviolet radiation can cause sunburn or cancer depending on our individual sensitivity. There is clearly a dose - response relationship between exposure and effect, with individual sensitivity playing an important role. Microwave and radiofrequency radiation are incredibly useful in heating and transmitting information. 

Ionizing radiation is far more dangerous than nonionizing radiation because it can directly damage cellular DNA and proteins, causing cell death or possibly cancer.
