imes the radioactive materials that are in standard nuclear warheads . Radioactivity destroys life , especially human life . A person exposed to a high level of radiation will die within 48 hours of exposure either due to infectious diseases caused by the destruction of the body's immune system from the radiation or by massive tissue bleeding . Humans above all other species are the most susceptible to radiation . Cockroaches and other types of insects can withstand 200 times more radiation exposure than humans before cancer or death occur , Radiation alters the electrical charge of the body's cells and allows cancer to form in the cells . Not all exposures to radiation cause cancer . The radiation may cause an incubation period of up to 40 years before full-blown cancer is diagnosed in the patient . By this time it is impossible to discover if it is cancer caused by radiation or not . Different doses of radiation will cause different problems . A dose of 2000 - 3000 REMs ( Roentgen Equivalent Man ) will cause brain tissue to swell , hemorrhage and will cause death . Fivehundred REMs will stop the cells from dividing , will cause hair to fall out , and will cause ulcers to form on the skin . It also destroys the white blood cells and platelets that help to fight off disease and stop bleeding in the body . Besides cancer radiation causes genetic defects and mutations in humans and other animals . These defects may lie dormant in one generation and reappear in the next . This create serious problems in the gene pool of the society by creating mutations and deformities .Recessive mutations may also occur these are lack of vigor and energy , susceptibility to disease , and mental deficiency in humans . It is estimated that for every one visible genetic mutation or defect there are 10,000 non-visible recessive mutations that contaminate the gene pool of society . This could lead to more mutations and unnecessary deaths because the human ...
