THE ENVIRONMENTAL MONITORING OF THE NATURAL RADIATION BACKGROUND IN ANTARCTICA WITH LIF-MG,CU,P TLD AND X-GAMMA RADIOMETRY

This paper describes the experimental results obtained with an X-gamma radiometer and LiF:Mg,Cu,P thermoluminescence detectors for the measu rement of natural radiation in the Antarctic region (China Zhongshan S tation). Two methods were adopted for the investigation: (1) thermolum inescence detectors for integrated dose; (2) X-gamma radiometer (type BH3013) for the distribution of the dose rare. The experimental result s show that the distribution of natural radiation levels in Antarctica is very uneven. The maximum difference in the values of the dose rate observed was 20 times. Further studies are needed to explain these re sults fully.
