Nuclear Track Detectors for Environmental Studies and Radiation Monitoring

Several improvements were made for Nuclear Track Detectors (NTDs) used for environmental studies and for particle searches. A new method was used to determine the bulk etch rate of CR39 and Makrofol NTDs. It is based on the simultaneous measurement of the diameter and of the height of etch-pit cones caused by relativistic heavy ions (158 A GeV Pb and In ions) and their fragments. The use of alc...

Applications of Nuclear Track Detectors in Radiation-Protection Monitoring

The present paper deals with the solid state etch-track detectors and their applications to the detection/dosimetry of neutrons, radon, and radon-decay products. Most of the scientists, actively engaged in the late 60’s and in the 70’s for monitoring the occupational neutron-exposure by etch-track detectors, became also involved in the development of personal monitors for the exposure to radon-...

Nuclear Track Detectors

Approximately half of the human exposure to radiation is due to indoor airborne shortlived progeny (decay products) of the radon gas (Rn). To measure the airborne concentrations of radon gas and/or its progeny, Nuclear Track Detectors (NTDs) are usually employed. The NTDs register the alpha particles emitted by radon gas and its progeny in the form of tracks in the NTDs, which will become visib...

Nuclear Track Detectors for Particle Searches

In this paper we report a search for intermediate mass magnetic monopoles and nuclearites using CR39 and Makrofol Nuclear Track Detectors (NTDs) of the SLIM large area experiment, 440 m exposed at the high altitude laboratory of Chacaltaya (Bolivia) and about 100 m at Koksil, Himalaya (Pakistan). We discuss the new chemical etching and improved analysis of the SLIM CR39 sheets. Preliminary limi...
