Superheaded drop bubble neutron dosimeter performance in a work environment

Bubble dosimeters offer a unique combination of sensitivity, immediate results, and dose-equivalent response, but their use has been limited by temperature and vibration. To determine their practicality, the authors simulated a large operation in an air-conditioned radiation work environment. One hundred and twenty devices of three types were tested. The batch homogeneity and reproducibility were about 20 %, and the lower limit of detection was about 10 μSv (1 mrem). The dose equivalent indicated by bubble dosimeters agreed with remmeters and spectrometers more closely than did the dose indicated by conventional dosimeters
