In the case of an air burst practically all of the radioactivity will go into ti.c strutosphere and from there deposite unifornly. The author calculates that the contribu- tion of radioactivity from weapons test is small, considerably less than the radiation exposure receive from natural sources of radioactivity, if the tests continue at the present level. However, in the case of a full scale hydrogen bor.b war with 1000 tines the present number of hydrogen bonbs exploded, the hemisphere contamination would correspond to a dose of about 25 r which could be damaging to future generations. Operation of nuclear plants for power, althou sources of large amounts of radiation can be controll to mininize the radiation levels to the population. The major source of such contamination, radioactive wastes, can be handled through separation of the more hazardous strontium and cesium fron the bulk of the wastes, storage of the residue for about 10 years followed by controlled release, and utilization of th separated cesium and strontiun as by-product material pending development of more satisfactory methods of handling and disposal.
