Color-change and ESR dosimetry based on redox changes of stable radicals of metallodiphthalocyanines in organic solutions
The main dosimetry characteristics of new liquid systems consisting of Lu, Hf and Zr diphthalocyanine solutions in ethanol, chloroform and their mixtures are investigated. These systems are suitable for measurements of doses of photon and electron radiation and fast neutrons in the absorbed-dose range from 0.002 to 100 kGy at dose rates from 1.5 × 10−3 to 3 × 106 Gy/s. The new systems can be used to manufacture compact detectors which acquire absorbed dose information both by measuring their responses with electron spin resonance (ESR) spectrometry or with visible spectrophotometry, and visually by solution color change.
