A modification of a beta detector is discussed. The apparatus detects radioactive particle emission from a wire or tape inside a vessel adapted to be pressurized. The apparatus consists of a scintillation-emitting, particle sensitive phosphor shaped to embrace the wire inside the vessel and a scintillation guide penetrating and sealed in the wall of the vessel for transmitting scintillations through the wall. The inside of the phosphor is lined with a material having a beta particle absorption characteristic such that it is capable of transmitting a measurable fraction of beta particles from decaying fission products while absorbing substantially all beta particles derived from Ar/sup 4//sup 1/. The device is suitable for monitoring coolant gas passing through a nuclear reactor. (N.W.R.)
