[en] The results of 'Comparison of TLD Measuring for Environment', which were attended by many domestic department in 2005, were introduced in this paper. It can be seen from the measuring results that the deviation is litter than ±10.1% when the estimate value of the nature radiation's kerma is compared to the average value gotten by standard ionization chamber, and the deviation is less than ±16.2% when the estimate value of two groups of TLDs those measuring γ radiation in laboratory is compared to the conventional true value in standard radiation Field. The fading correction and its corresponding calculation method were specially introduced in this paper for improving the accuracy of the environment cumulate kerma. (authors)
