400 kHz was used to assess the occupational exposure levels to the GMF for 1.5 and 3.0 Tesla MRI body scanners, using the method of the WP according to the International Commission on Non-Ionizing Radiation Protection (ICNIRP) ... F Bonutti,M Tecchio,M Maieron,... - 《Radiat Prot Dosimet...
Attempts have been made to use data on therapeutic uses of radiation to address the issue. There are few such studies with a large enough data sample. Some of these suggest that there is a dose below which there is no effect. But there are potential biases in such a study in that physi...
aCells from blood vessel walls in the brain were placed in culture dishes and subjected in the laboratory to mobile phone radiation of two watts per kilogram, the maximum allowed internationally for cellular phones. After an hour's exposure, biochemical changes were seen in the cells that could...
Residents of the Techa riverside villages chronically exposed to ionizing radiation (the average dose rate in 1951-1956 was 0.047 Gy/year, the maximum reached 2.44 Gy/year) developed marked changes in the cellular composition of peripheral blood. The maximum reduction of peripheral blood counts occ...
RADIATION MANAGEMENT SOLUTION FOR MAXIMUM ALLOWED EXPOSUREApparatuses, systems, and methods for a user equipment device (UE) to perform methods for triggering a change in beam configuration based on UL beam conditions. The UE may detect an unsafe UL beam condition for an UL beam based, at least...
Radiofrequency radiation, Part 1: Maximum exposure levels - 100 kHz to 300 GHzdoi:AS 2772.1-1990规定了人体暴露于射频辐射的极限,旨在避免在100 kHz至300 GHz的频率范围内对人体有害的生物效应.本标准适用于辐射工作人员的职业接触和公众的偶然接触.它不适用于为医疗诊断或治疗而对患者进行的辐照,也没有对...
Current interest in laser radiation safety requires demonstration that a laser system has been designed to prevent exposure to levels of laser radiation exceeding the Maximum Permissible Exposure. In some simple systems it is possible to prove this by calculation, but in most cases it is preferable...
effect of straight metalworking fluids exposure on colon cancer risk The reasons for the inconsistencies between our findings and those in the aerospace cohort are not clear but suggest that our adjustment for time-varying confounding affected by prior exposure using TMLE may have allowed us to ...
