  3. The key problems on studies of passive and integrated thoron monitoring methods are to set up a thoron chamber for the conditional experiments and the calibration of thoron dosimeters, develop methods for discriminating thoron from radon and for the effective dose evaluation of thoron daughters base on thoron exposure

    研究被動積分測（氣土）技術的關鍵在於研究用於條件實驗和刻度的（氣土）室刻度系統、甄別氡的方法和由（氣土）暴露量估算（氣土）子體所致有效劑量的方法。
  4. Although thoron is one of isotopes of radon, and the characteristics of thoron and thoron progenies are similar to those of radon and radon progenies, because the half life of thoron is shorter ( 55. 6s ), the concentrations of thoron and thoron daughters in environment are lower, people usually think that the effective dose from thoron and its progenies can be eliminated, and the measurements of thoron progenies concentrations are difficulty, a little research work on the dose evaluation of thoron and thoron progenies in environment has been done

    雖然（氣土）是氡的同位素，它及其子體的特性也與氡及其子體的相似，但由於（氣土）的半衰期短（ 55 6s ） ，環境中（氣土）濃度較低， （氣土）及其子體濃度的測量較難，人們一般認為（氣土）及其子體所致劑量可以忽略，所以對環境中（氣土）及其子體劑量評價研究很少。

  9. The evaluated results in unscear 1993 report indicate that more than half of effective dose of nature radiation exposure to the human being comes from radon and its daughters, so the studies on radon and radon daughters have widely gotten attention in the field of radiation protection more than half century

    根據unscear1993年報告的估算，人類受到的天然輻射一半以上來自氡及其子體的貢獻，所以半個世紀以來氡及其子體一直是天然輻射領域研究的熱點。
  10. In order to solve problems existing in current measuring methods for radon exhalation rate ( such as the effect of unequilibrium radon and its progeny, humidity effect, leak and back - diffusion effect, etc. ), based on the principle of surveying radon and its progeny in the medium surface, a rapid arid accurate method for measuring radon exhalation rate taking advantage of the rad7 radon detector was established
