It has been reported that superheated drops made of R-12 at room temperature are sensitive to neutrons yet insensitive to photons. This property makes its use attractive as one of the most useful neutron dosimeters. The photon sensitivity of R-12 at room temperature (25°C) when exposed to 59.54 keV photons obtained from radioactive 241Am has been noted for the first time in our laboratory. This discovery is of importance not only from the point of view of basic science but also to the users of R-12 in neutron dosimetry in assessing the neutron dose correctly. This discovery also indicates a new direction of investigation with R-12 detector.
