Absorbed Dose Rate 中文

Unit:nGy/h, nSv/h
Name Space City Value Time

• The air absorbed dose rate issued by National Radiation Environmental Data Evaluation System includes the environmental surface gamma radiation dose rate of the instrument's response to cosmic rays, in unit of gray per hour (Gy•h-1). Air absorbed dose rate is an important part of environmental radiation monitoring since it is a measurement that can directly, quickly, and continuously reflect the environmental radiation levels.

• The background level of air absorbed dose rate is various in different region since the geology, latitude and longitude, and environmental conditions are changed.

• The fluctuations in air absorbed dose rate in the same monitoring station are also non-negligible. The fluctuations are related to various environmental factors such as groundwater level, soil moisture, precipitation, ice and snow coverage, ground subsidence of radioactive materials, ejection and diffusion of radioactive gases, etc.

•The unit of air absorbed dose rate issued by National Radiation Environmental Data Evaluation System is nGy/h,1Gy=109nGy.
