| Abstract: | According to the transitive relation of quantity, it introduces the mathematical model of quantity transfer. According to the mathematical model, it introduces the uncertainty evaluation method of verification result. By Combining RAD-7 verification according to Verification Regulation of the Radon Measuring Instruments, it evaluates the related combined standard uncertainty of the volume activity response. It shows, the uncertainty of the verification result is mainly affected by the effect of radon transfer from the liquid radium source and verified instruments counting ability. |
