Plastic Scintillators for Radiation Detection
Overview

Plastic scintillators, the main imported component of the radiation detectors, have been successfully synthesized by controlled thermal polymerization of monomers, such as styrene, vinyl toluene, vinyl xylene, etc., in the presence of suitable initiator and fluorescence additives. The scintillator samples produced were of cylindrical shape with 2 inch diameter and different heights. The process is capable of producing the same in any required shape and size.

Sound financial background parties, having fume hood facilities and preferably experience in polymerization of vinyl monomers, are invited.

Quick View Leaflet

Plastic scintillators are the main imported component of radiation detectors. The indigenous development of the plastic scintillators, based on polymers like polystyrene, polyvinyl toluene and polyvinyl xylene, has been carried out. These scintillators are developed by controlled polymerization of corresponding monomers in the presence of suitable initiators and organic fluorescence additives. The cylindrical shaped 2 inch diameter plastic scintillators of different heights have been successfully made. These scintillators can be used for making radiation monitors for target applications, such as low range survey monitoring, contamination monitoring, etc. Performance of the radiation monitor is matching well with that of the imported ones.

SPECIFICATIONS

  • Crystal Dimensions : 2 inch diameter and height in the range of 0.5 to 3.0 inch

  • Density : 1.05 g/cm3

  • Melting Point : ~240°C

  • Wavelength of emission : 385 nm

  • Sensitivity for 137Cs : 0.6 cps/µR/hr

APPLICATIONS

  • Radiation detectors

  • Low range survey monitors

  • Contamination monitors

  • Nuclear physics experiments

  • Area monitor

  • Security baggage scanning
