Indoor radon concentration and public dose evaluation in Ningxia Hui Autonomous Region, China.
The indoor radon concentration in a total of 143 rooms from 82 urban and 61 rural households in Ningxia was measured using the solid nuclear track method over four quarters for 1 y, followed by calculation of the annual effective dose. The results indicated that the mean of indoor radon concentrations was 88 Bq m-3, with a range from 39 to 226 Bq m-3. The concentrations exceeded 100 Bq/m-3 in 30% of the measurement locations, with two points measuring above 200 Bq/m-3, accounting for 1.4%. The indoor radon concentration was higher in rural areas compared to urban areas. Moreover, it exhibited a seasonal variation, with the highest levels observed during winter and the lowest during summer. Additionally, the effective dose of indoor radon among residents in Ningxia was calculated at 2.20 mSv a-1.
期刊介绍：
Radiation Protection Dosimetry covers all aspects of personal and environmental dosimetry and monitoring, for both ionising and non-ionising radiations. This includes biological aspects, physical concepts, biophysical dosimetry, external and internal personal dosimetry and monitoring, environmental and workplace monitoring, accident dosimetry, and dosimetry related to the protection of patients. Particular emphasis is placed on papers covering the fundamentals of dosimetry; units, radiation quantities and conversion factors. Papers covering archaeological dating are included only if the fundamental measurement method or technique, such as thermoluminescence, has direct application to personal dosimetry measurements. Papers covering the dosimetric aspects of radon or other naturally occurring radioactive materials and low level radiation are included. Animal experiments and ecological sample measurements are not included unless there is a significant relevant content reason.
