Dose rate dependency of electronic personal dosemeters measuring x- and γ-ray radiation

Three models of EPDs Siemens Mk 2.3, Rados RAD-60S, and Vertec Bleeper Sv were irradiated with seven photon beam qualities: Co, Cs, and the ISO narrow spectrum series x-ray qualities N-250, N-200, N-150, N-60 and N-20. The personal dose equivalent rates delivered to the devices varied in the range between 0.002 and 0.25 mSv/s. Measurements were made with the EPDs mounted free-in-air as well as ...

Assessment of effective radiation dose of an extremity CBCT, MSCT and conventional X ray for knee area using MOSFET dosemeters.

The objective of this study was to assess and compare the organ and effective doses in the knee area resulting from different commercially available multislice computed tomography devices (MSCT), one cone beam computed tomography device (CBCT) and one conventional X-ray radiography device using MOSFET dosemeters and an anthropomorphic RANDO knee phantom. Measurements of the MSCT devices resulte...

X-ray radiation and the risk of multiple sclerosis: Do the site and dose of exposure matter?

  Background: The sporadic cases of radiation-activated multiple sclerosis (MS) has been previously described, with a few studies focused on the relationship between radiation and the risk of MS. The aim of our study was to evaluate the association between history of X-ray radiation and MS.   Methods : This case-control study was conducted on 150 individuals including 65 MS patients and 85 age-...

Genotoxic effects of high dose rate X‐ray and low dose rate gamma radiation in ApcMin/+ mice

Risk estimates for radiation-induced cancer in humans are based on epidemiological data largely drawn from the Japanese atomic bomb survivor studies, which received an acute high dose rate (HDR) ionising radiation. Limited knowledge exists about the effects of chronic low dose rate (LDR) exposure, particularly with respect to the application of the dose and dose rate effectiveness factor. As pa...

Absorbed dose measurements of a handheld 50 kVP X-ray source in water with thermoluminescence dosemeters.

Absorbed dose rate measurements of a 50 kV(p) handheld X-ray probe source in a water phantom are described. The X-ray generator is capable of currents of up to 40 microA, and is designed for cranial brachytherapy and intraoperative applications with applicators. The measurements were performed in a computer-controlled water phantom in which both the source and the detectors are mounted. Two dif...
