[Background]Nuclear sites require monitoring of artificial radioactive aerosols,but existing instruments often encounter the problem of"measurement uncertainty(radon progeny interference)"in the measurement of artificial radioactive aerosols,requiring effective calibration of radon daughter interference levels.[Purpose]This study aims to accurately calibrate the radon progeny measurement instruments and effectively calibratt the radon progeny aerosol interference levels for artificial radioactive aerosol monitoring instruments.[Methods]Based on...
