Abstract
The neutron sensor based on superheated droplets, developed in the U.S.A. and U.K., is one of the most attractive techniques at present for neutron radiation dosimetry. Limited shelf life, i.e. six months (BTI, U.K.), and the dependence of neutron response on climatic conditions are some of the problems associated with these sensors. The development of the above type of sensor suitable for tropical conditions is therefore required. The authors have begun to develop such sensors. The preliminary results show a lower limit of detection of 10 μSv for an
241Am-Be neutron source and a linear response from 10 μSv to 1 mSv has been reported.
