A sensitive neutron dosimeter using superheated liquid

The present work relates to a sensitive neutron dosimeter, a device for monitoring neutron dose in some accelerator and reactor sites. This device is capable of measuring a neutron dose as small as 0.1 μSv using superheated liquid as a sensitive liquid. The nucleation was measured by the volumetric method developed in our laboratory. The dose response of superheated drops of four liquids having boiling points of 8.92, −29.79, −40.75 and −45.6°C, irradiated by a 3 Ci Am–Be neutron source has also been presented in this article.
