Advanced materials in radiation dosimetry

High charge-carrier mobilities in blends of poly(triarylamine) and TIPS-pentacene leading to better performing X-ray sensors

“…Furthermore, the elemental composition of most polymers (C, H, N and O) makes them an ideal candidate for dosimeters in medical applications, in which the detector requires a "human tissue-equivalent" interaction with radiation. (The average atomic number of muscle tissue is 7.4 [18].) Although radiotherapy and medical applications would benefit greatly from the improved accuracy of tissue-equivalent dosimeters, there are currently no low-cost, largearea devices with tissue-equivalence available.…”

Effect of heavy proton and neutron irradiations on epitaxial 4H-SiC Schottky diodes

“…Silicon carbide (4H-SiC) radiation detectors are being developed for a variety of applications including particle detection [1,2], radiation dosimetry [3], X-ray [4] and UV detection [5]. The wide bandgap of 4H-SiC (3. elevated temperature and intense radiation environments [6].…”

Investigation of the suitability of commercially available CVD diamond for megavoltage X-ray dosimetry

“…Values between 18 and 164 nC·Gy -1 ·mm -3 have been reported for detectors based on HPHT diamonds [14]. [36]. Other values reported include 330 nC·Gy -1 ·mm -3 for an epitaxial SiC diode [36] and 128-480 nC·Gy -1 ·mm -3 for polymer-based detectors [37].…”
