Studies are being done with animals, but it is difficult to translate the effects of microwaves on animals to possible effects on humans. One pertinent characteristic of microwaves is that they disperse and dissipate very quickly in the atmosphere. However, as Figure 3-1 illustrates, as you move away from the oven, the level of exposure to any energy that may be leaking decreases dramatically. However, it must be noted that Czech scientists have reported some effects even at these infinitesimal levels. Stay at least an arm s length away from the front of an operating oven.
Children represent another sensitive segment of the population.
Never operate an oven when it is empty. Never inactivate, interfere with, or try to adjust the built-in safety interlock system of an oven, unless you are properly equipped and qualified to do so. The Food and Drug Administration recommends that microwave ovens not be used in home canning. It is believed that they do not produce or maintain temperatures high enough to kill harmful bacteria. Observing these safety suggestions, as well as others that will be presented in subsequent chapters of this book, will help to minimize exposure levels and the risk of serious accidents.
