Abstract
It is an objective of the present invention to provide a scintillation counter that can measure the intensity of only .beta. rays. Two scintillation fibers (11 and 12) which emit different wavelengths are provided in series to a probe (10). One of the scintillation fibers (12) is covered with a .beta.-ray shield. The optical signal generated at the probe (10) is transmitted through the optical fiber (20) and separated by the light separating element (31). One portion of the separated optical signal is incident on a light detector (32) and the intensity of the incident light detected. The other portion of the separated optical signal is incident on a light detector (33) and the intensity of the incident light detected.
