Abstract

Beta-ray emitters, for example, C/14/, H/3/, P/29/, and S/35/ are useful in tracer studies. However, energetic considerations of these radioactive species often times require dissolution techniques combined with sensitive scintillation techniques to measure gross effects.

A Radiation Dosimeter

Beta-ray emitters, for example, C/14/, H/3/, P/29/, and S/35/ are useful in tracer studies. However, energetic considerations of these radioactive species often times require dissolution techniques combined with sensitive scintillation techniques to measure gross effects.

Thermoplastics (plasticized and unplasticized) are useful as detectors for these electrostatic charges. Thermoplastics useful for this purpose are polystyrene, polymethylmethacrylate, polyvinyltoluene, poly (n - propylmethacrylate), butadiene - vinyl toluene (10/90) copolymer, polyvinylchloride, polymethylacrylonitrile, polyvinylacetate. An accumulation of charge distribution on the thermoplastic material is used to create impressions which show differences in the concentration of the radioactive tracer. Localized effects can also be noted.

Development of deformations and method of optical readout is accomplished using the technique described by W. E. Glenn and J. Edmond Wolfe in International Science and Technology, June 1962, pp. 28-35, entitled Thermoplastic Recording.
