【Abstract】 Techniques and methods on continuous monitoring the Y radiation dose rate due to the effluence from nuclear facilities with a high pressure argon ionization chamber have been described. About 33450 individual record data for three years (1990~1992) have been obtained by a continuous monitor in the environment near the two reactors (15 MW heay water reactor and 3. 5 MW light water swimming pool reactor). These date have given the external dose caused by noble gas plume from the ractors. The maximum value of annual effective dose is 53.8 uSv in 1992, which is only equal to 9 % of natural background level. The monitoring results have compared with the computed results for the finite cloud atmospheric diffusion models, and they are in agreement within 62%.更多还原
