Mostly natural sources contribute to the ionizing radiation exposure that people undergo aU the time. The received dose of radiation is measured in grays. The absorbed dose of radiation that results in damage done to organisms is measured in sieverts.

OSHA considers skin diseases as illnesses caused by exposure to chemicals, plants, or other hazardous substances. OSHA dehnes respiratory conditions or illnesses as breathing-related problems associated with pneumonitis, pharyngitis, rhinitis, farmer s lung, beryllium disease, tuberculosis, occupational asthma, reactive airways dysfunction syndrome, chronic obstructive pulmonary disease, and hypersensitivity. Examples can include heatstroke, hypothermia, decompression sickness, effects of ionizing radiation, exposure to ultraviolet (UV) rays, anthrax, and bloodbome pathogen diseases. 

Ionizing radiation can draw a considerable emotional response from the public. Major events involving ionizing radiation stir public concerns. Many factors contribute to this response. There are fears developed from the devastation of atomic bombs dropped on Japan in World War II. There is fear of potential use of atomic weapons by the military and terrorists. There is fear of cancer and other health effects from ionizing radiation exposures.
