Uranium 238 U238 Radioactive DecayHere we are concerned mainly with ionising radiation from the atomic nucleus It occurs in two forms rays and particles at the high frequency end of the energy Io. The US Environmental Protection Agency EPA is responsible for advising the government on radiation hazards and regulating certain sources of radioactivity in the environment This booklet provides basic facts about radiation science as well as inform internal emitter iodine radium strontium tritium cesium absorbed dose rate kg MeV MeV brPage 4br Health effects depend on how radiation interacts w th bio ogical material at the microscopic level Radiation delivers energy in small pa ckets not unifo Learning Objectives.
