background: a substantial part of the public’s natural radiation dose is due to the inhalation of radon gas. most of the exposure occurs indoors where the airborne concentration of radon and its decay products is usually higher than outdoors. materials and methods: radon activity concentration has been measured twice in 50 classrooms in 5 levels (10 each) during summer and winter using solid-st...
Radiation detection is essential for determining of radiation dose. Depend on the detector and dosimetry method, detection process is performed in different levels. Pulse counting is the first level of detection. Typically, the output of a radiation detector for determining value of the radiation dose cannot be used directly. Through changing the response function or the readout detector, is tr...
introduction natural and artificial radionuclides are the main sources of human radiation exposure. these radionuclides, which are present in the environment, can enter the food chain. rice is one of the most important food components in iran. radionuclides by transferring from soil to rice and entering the human body can affect human health. materials and methods fourteen samples of different ...
In this project the neutron spectra from the reaction of deutron on beryllium muclei is measured. The energies of deuterons were 7, 10, 13 and 15 MeV, and these measurements are performed at 10, 30 and 50 degrees relative to the beam of deutrons. The detector used is 76 by 76 mm right circular cylender of NE-213 liquid scintillator. The zero crossing technique is used for gamma discriminatin....

Background: To determine the basic physical and dosimetric properties of a new synthetic single-crystal diamond detector and its application for relative small field dosimetry. Materials and Methods: The pre-irradiation dose required to stabilize detector response, dose rate dependence, photon and electron energy dependence, temperature dependence and angular dependence of MicroDiamond detector...
Radiation detector systems in nuclear medicine imaging A radiation detector system in nuclear medicine imaging is definitely a timely topic or area of research where not many papers are available in the literature of nuclear medicine imaging. Arguably, no single device can detect all kinds of radiation and no one device is useful in all situations. Understanding of the principles of radiation d...
Centre for Medical Radiation Physics (CMRP) is a research strength at the University of Wollongong, the main research theme of this centre is to develop prototype novel radiation dosimeters. Multiple detector systems have been developed by Prof Rosenfelds’ group for various radiation detector applications. This paper focuses on four current detector systems being developed and studied at CMRP. ...
Room-temperature detector, manufactured by the company ‘‘SPINOR’’ (Tomsk Russia) was tested for the investigations of the coherent synchrotron radiation characteristics at the bent electron beam of FLASH (Hamburg) in the wavelength region 0.5–3mm. Detector is based on a low-threshold diode and a broadband antenna with a built-in preamplifier. The detector characteristics allowed us to measure a...
