Effects Nonionizing Radiations

Atmospheric deposition of Cs from Chernobyl to vegetation and eventually to the milk of sheep, cows, and goats on contaminated silage was reported in Italy, the Netherlands, Japan, and the United Kingdom. The effective half-life of Cs was 6.7 days in silage and 

6 days in milk. The average daily transfer coefficient of Cs and Cs from Chernobyl from a 70% grass silage diet to milk of Dutch dairy cows was about 0.25%/L. In goats Capra sp.), about 12% of orally administered Cs was collected in milk within 7 days after dosing. 

Investigations of the cellular effects of radiofrequency radiation provide evidence of damage to various types of avian and mammalian cells. These effects involve radiofrequency interactions with cell membranes, especially the plasma membrane. Effects include alterations in membrane cation transport, Na /K -ATPase activity, protein 

Microwaves inhibit thymidine incorporation by DNA blockage in cultured cells of the Chinese hamster irradiated cells had a higher frequency of chromosome lesions. Microwaves induce teratogenic effects in mice when the intensity of exposure places a thermal burden on the dams and fetuses, resulting in a reduction in fetal body mass and an increased number of resorptions.

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.
