摘要

In this paper, a method and its device were designed to quickly adjust the effective decay constant λEFF of a radon exhalation simulation device. The device achieves the purpose of adjusting λEFF by actively adjusting the leakage rate of the device. The λEFF of the initial radon exhalation simulation device was measured firstly. then five different sets of λEFF adjustment experiments were set. The error between the actual value of λEFF and the target value of λEFF calculated from the five experiments was within 2 standard deviations. This shows that the method of adjusting λEFF of the device is correct.
