People exposed to radiation should remove their clothes as soon as possible and place them in a sealed container or bag . The evidence that low dose radiation may induce these tumors in humans is much more convincing and is derived mainly from studies of people exposed to the effects of the atomic bomb at Hiroshima . Exposure to radiation can lead to skin cancer , most commonly this comes from exposure to the sun . Without the viscous dissipation which occurs in disks , matter would fall into the hole heated up by simple adiabatic compression , and efficiency of conversion of gravitational energy in radiation would be very small . Any radiation can lead to changes in the germ plasm . We did n't realize just what levels of radiation would be considered dangerous or whether it was possible they could be decontaminated . Exposure to ionizing radiation can come from many sources . Overexposure to high amounts of ionizing radiation can lead to effects like skin burns , hair loss , birth defects , cancer , mental retardation ( a complex central nervous system functional abnorm ality ) , and death .
