ABSTARCT The atmospheric gamma radiation level in gas flaring environment has gained the attention of researchers and environmentalists due to its devastating impact both on the climate and the environment. It is important to make a quantitative assessment of the gamma radiation in the gas flaring environment and nearby residential areas. In situ measurements of the gamma radiation were perform...

Double-exposure digital holographic interferometry is a powerful and widespread technique for fine measurement of the induced changes in special physical properties, like density, refractive index and etc. In this paper, application of this technique for measuring the absorbed dose from an electron radiation source in poly (methyl methacrylate) material is studied through modeling. The method o...

Here we describe the first clinical experiences regarding the use of an automated radiation dose management software to monitor the radiation dose of patients during routine examinations. Many software solutions for monitoring radiation dose have emerged in the last decade. The continuous progress in radiological techniques, new scan features, scanner generations and protocols are the primary c...

This review paper presents an overview of individual monitoring, as well as the national dose register and dose record management of radiation workers in China. Progress has recently been made on the individual monitoring of radiation workers. A critical analysis of current status and problems in individual monitoring is also presented and necessary future research on individual monitoring, suc...

The radiation monitoring network in the Netherlands is designed to detect and track increased radiation levels, dose rate more specifically, in 10-minute intervals. The network consists of 153 monitoring stations. Washout of radon progeny by rainfall is the most important cause of natural variations in dose rate. The increase in dose rate at a given time is a function of the amount of progeny d...

monitoring the effective parameters of drying crops is necessary to evaluate and determine system performance under real conditions. hence, a monitoring system was constructed to determine the performance of a vegetation forced-convection solar dryer. digital temperature sensors were set up in the air inlet and outlet of the collector and the air outlet of the drying chamber. a program was writ...
