DEVELOPMENT OF EMERGENCY MONITORING SYSTEM FOR ALPHA-PARTICLE-EMITTING RADIONUCLIDES IN THE AIR

During the early phase of a nuclear accident, major radioactive materials are released into the environment, necessitating the prompt deployment of various protective actions to avoid or reduce radiation exposure. To implement these actions, the levels of radioactivity in the environment should be determined. However, the radioactivity concentrations of artificial alpha-particle-emitting radionuclides such as plutonium are difficult to measure...
