چکیده

2014 MOS transistors are used for radiation dosimetry. The sensitivity obtained is ranging between 20 mV/ Gray (SiO2) and 1,5 V/Gray (SiO2). Good linearity and stability of the transistor response is obtained. Revue Phys. Appl. 21 (1986) 283-287 AVRIL 1986, Classification Physics Abstracts 73. 60D

Temperature effects and accuracy of MOS radiation dosimeters

-The influence of the irradiation dose on the parameters which control the temperature sensitivity of thick oxide p-MOS ionising radiation dosimeters is investigated. The temperature sensitivity of the threshold voltage, the carrier mobility and the minimum temperature coefficient current appear to be dose-dependent contrary to what is generally considered. The consequences on the dose measurem...

A Validation Study on Radiation properties of a Novel LiF: Mg, Ti Known as IAP-100

Introduction: LiF dosimeter has the most application in medicine. This study aimed to evaluate some dosimetric properties of a novel LiF: Mg, Ti. Materials and Methods: An ELEKTA Precise linear accelerator was used to calibrate dosimeters at 6 MV. In this survey, responses of dosimeters were evaluated up to 1000 cGy. Background effect was investigated in two different dosimeter states includin...

Evaluation of a low-cost commercial mosfet as radiation dosimeter

In this work, a low-power commercial MOS transistor was tested as a gamma radiation dosimeter. Due to the small size of its detector, low cost, reproducibility, minimal power requirements, signal conditioning and data processing, it offers excellent possibilities as a dose monitor in radiotherapy. Sensor irradiation in the unbiased mode was aimed at improving patient comfort and facilitating us...

Flexible radiation dosimeters incorporating semiconducting polymer thick films

Flexible radiation dosimeters have been produced incorporating thick films (>1 μm) of the semiconducting polymer poly([9,9-dioctylfluorenyl-2,7-diyl]-co-bithiophene). Diode structures produced on aluminium-metallised poly(imide) substrates, and with gold top contacts, have been examined with respect to their electrical properties. The results suggest that a Schottky conduction mechanism occurs ...

Radiological properties of nanocomposite Fricke gel dosimeters for heavy ion beams

The radiological properties of nanocomposite Fricke gel (NC-FG) dosimeters prepared with different concentrations of nano-clay, perchloric acid and ferrous ions in deaerated conditions were investigated under carbon and argon ion beam irradiation covering a linear-energy-transfer (LET) range of 10 to 3000 eV/nm. We found that NC-FG exhibits radiological properties distinct from those of convent...
