Safety standards may be limited in scope...
The term critical organ was used to identify the particular organ that first attains the critical concentration of a metal under specified circumstances of exposure and for a given population. This definition differs from other ones used in radiation protection, in which the term critical organ ...
CHAPTER 1 General provisions Maximum values for radiation exposureTreaty, The Euratom
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...
Investigations have been started on the correlation between maximum allowable quantities of a radioisotope in the body and in the expired air. Knowledge of these correlations may be of great importance in preventing darnage due to ionizing radiations. 288 ...
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...
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...
In order to find the maximum allowable shear stress a length of tube was tested in tension and reached the limit of proportionality at 21 kN. Assuming the criterion for elastic failure to be the maximum shear stress, find the greatest torque to which the shaft could be subjected. [98.2 N ...
