title: A new ESR dosimeter based on polytetrafluoroethylene
abstract: A new electron spin resonance (ESR) dosimetry system based on the ESR response of polytetrafluoroethylene is presented. The dose response of these dosimeters irradiated with 60Co gamma radiation was linear in the range from 6 x 10(2) up to 1.5 x 10(5) Gy, having a repeatability of +/-1% and a high degree of reliability (Cf = 1.054). The persistence of the signal was monitored over a period of one month. ESR signal decay was 5-7% in the temperature range from room temperature up to 40 degrees C.
