Research on the Measurement of X-γ Accumulated Radiation Dose in the Environment of Jinan City and the Comparison of Instantaneous Dose Values
With the development of nuclear technology and the advancement of environmental radiation monitoring methods,the detection of γ external radiation in radiation environments has been widely used in the environment since the 1990s.The TLD detection,represented by LiF(Mg.Cu.p)detectors for external radiation dose detection,has made rapid progress in cumulative dose measurement.The cumulative dose measurement method can provide environmental radiation dose data for a certain period of time,and has become one of the main methods of environmental radiation detection.It can reflect the external radiation level of the tested site during a certain period of time,and its detection data is accurate and the information is relatively accurate.Therefore,it can judge the quality of the external radiation environment and the corresponding changes in external radiation dose received by personnel.However,due to the complexity of radiation elements in the natural environment,weak emission ability,and multiple interference conditions in on-site measurements,it is usually necessary to use two or more detection methods after conducting natural environment radiation detection,and compare and confirm them with each other.Therefore,X-γ radiation environmental monitoring combines cumulative and instantaneous monitoring,providing comprehensive radiation dose data.
