The principle of present work lies on the dependence of the threshold neutron energy on the dimensionless quantity “degree of metastability (ss)” of superheated liquids. The response of the superheated emulsions consists of the drops of superheat

Superheated emulsions being inexpensive, easy to fabricate, and having tissue equivalent composition make them as one of the popular neutron dosemeters. One more advantage is that they can be made insensitive to gamma rays by the choice of the sensit
