X-ray machines that comply with the ISO requirements for calibrating personal dosimeters sometimes are not available in a world region, mainly in developing countries. This is used as an excuse for a lack of personal dosimeter calibration and, consequently, a lack of reliability in the individual monitoring programs. Considering the availability of x-ray machines in many hospitals, this work sh...

SIRAD badge dosimeters are a new type of personal dosimeter designed to measure radiation exposure up to 200 R and give a visual qualitative measurement of exposure. This is performed using the active dosimeter window, which contains a radiochromic material amalgamated in the badge assembly. When irradiated, the badges active window turns blue, which can be matched against the given colour char...

This work intend to identify and follow up quality control parameters to improve thermoluminescence dosemeter (TLD) system used for personal dosimetry in ionizing radiation metrology laboratory (IRML). Characterization of personal dosimetry system has presented in terms of the stability of reader calibration factors, linearity of response for Cs as reference radiation source, energy and angular...

Polysulphone has been widely used as a dosimeter to quantify personal solar UV exposures to humans during normal daily activities. In summer at sub-tropical and tropical latitudes, the dynamic range for UV exposures allows the use of the polysulphone to measure solar UV over periods of approximately three to six hours. The use of mesh as a filter over the polysulphone has been previously report...

A radiochromic silicone based dosimeter has been fabricated that allows for threedimensional (3D) dose verification. This paper characterizes the silicone dosimeter and verifies previous results found by other research groups. Using a recipe found to be dose rate independent, we identify the spectra of the dosimeter irradiated to different doses and verify that the response from different dose ...

The IAEA/RCA (Regional Cooperative Agreement) project to strengthen and harmonize radiation protection infrastructures in Asian and Pacific region started in 1988. The number of the RCA member countries is 17 at present. In the early stages of the project, there was little information on the status of radiation protection and their technical abilities of radiation protection measurements in RCA...
