The TSC thermogram, conduction current vs temperature or time, has current peaks that are proportional in height to irradiation. The peak height response to x rays is: (1) linear with doses from 10 mR to 100 R ( 60 Co energy); (2) useful from 10 mR to 10 4 R ( 60 Co energy); (3) reusable with no additional treatment for exposures less than 1000 R; (4) exposure rate independent from at least 0.12 mR/sec to 3.2 R/sec; (5) stable; and (6) reasonably similar to tissue response as a function of energy. The stability of response, simplicity of instrumentation requirements, and dependable supply of materials at competitive price with other dosimetry systems favor application of this technique.Read More
