Abstract
Provided is an apparatus for measuring radioactivity without loss of radioactive particles. The apparatus includes a sampler that collects a radioactive sample from an exhaust pipe, a sample detector that is provided adjacent to the exhaust pipe and includes a particle collecting filter and a first radioactivity detector, a sample transporting pipe that extends from the sample detector and transports the radioactive sample from which the radioactive particles have been removed, a sample transporting pump that is provided at the sample transporting pipe, and a gaseous radioactivity detector that is provided at the sample transporting pipe and detects a radioactivity of the radioactive sample from which the radioactive particles have been removed. The particle collecting filter filters out the radioactive particles from the radioactive sample and the first radioactivity detector detects a radioactivity of the radioactive particles filtered out by the particle collecting filter.
