Апстракт:
The gamma dose rate in the air was measured in 355 rooms in 17 inspected hospitals for rehabilitation on the Bulgarian territory. The maximum value of the parameter was 0.390 µSv/h and the minimum value was 0.06 µSv/h with the arithmetic mean 0.157 µSv/h (standard deviation - 0.160). The gamma dose rate is within the natural variations of the parameter in buildings. Direct measurements of radon were conducted and range of the results were from 12 Bq/m3 to 3920 Bq/m3. The relationship between the two parameters was examined. A weak correlation between gamma dose rate and indoor radon concentration was found. The measurement of gamma dose rate could be useful parameter for carrying out the radon workplace control.
