Who Is at Risk?
Since the early 1940s, millions of Americans have been exposed to asbestos in the course of their jobs in the construction trades and in military service. Although it is known that the risk to workers increases with heavier exposure and longer exposure times, asbestos-related illnesses have been found in individuals with only brief exposures. Because of the long latency period, no signs of illness may be apparent for 20 to 50 or more years.
Family members of workers heavily exposed to asbestos also face an increased risk of developing mesothelioma. This is most often the result of asbestos dust being brought into the home on the shoes, clothing, skin, and hair of workers. This type of exposure is referred to as paraoccupational or household exposure. There is also a risk of exposure from asbestos in nature.
It is important to remember that not everyone exposed to asbestos will develop diseases related to their exposure. In fact, many will experience no ill effects whatsoever. Asbestos that is bonded into finished products such as walls, tiles, and pipes poses no risk to health as long as these products are not damaged or disturbed in such a way that fibers are released into the air. It is when asbestos fibers are released and inhaled or digested that individuals are at risk for developing asbestos disease. Once these fibers work their way into body tissues, they may stay there indefinitely.
