Abstract
This study was performed to establish the analytical method of radium and radon in various environmental samples with the <TEX>${\gamma}$</TEX>-ray spectrometry. The major problem in the measurements of low level <TEX>${\gamma}$</TEX>-ray, such as environmental radioactivity, is the fluctuation of <TEX>${\gamma}$</TEX>-ray background spectrum. To overcome this problem, a nitrogen gas was filled up in the detector chamber to reduce the background counts due to airborne radioactivities, i.e., <TEX>$^{214}Pb$</TEX> and <TEX>$^{214}Bi$</TEX>, the daughters of <TEX>$^{222}Rn$</TEX> in air. When nitrogen gas flowed around the detector, peak counts of <TEX>${\gamma}$</TEX>-rays from the daughters of <TEX>$^{222}Rn$</TEX> decreased about 80% below 1 MeV and about 20~50% above 1 MeV. The use of nitrogen purging results in approximately tenfold increment of sensitivity.
