Comparison and analysis between cumulative dose and instantaneous does rate of Beijing

Measurements of the cumulative dose and instantaneous dose rate of indoor and outdoor environment respectively are done and the results are compared. The results indicate that the value of En for the cumulative dose and instantaneous dose rate of indoor is less than or equal to 1, so that the result is satisfactory; The relative deviation of cumulative dose rate and the instantaneous dose rate for Beijing environment in 2013 is less than 30%, so the comparison result is satisfactory too. This comparison, to some extent, verify the reliability of the measurement results based on two different principle for radiactive dose monitoring instruments, one for cumulative dose measurement system, the other for the instantaneous dose measurement instrument.
