在过去几年中，人们对氡和氡子体对我们健康的潜在有害影响表示了相当大的关注。氡衰变方案的复杂性质涉及到各种辐射的发射，包括几种[α]粒子、[β]粒子和[γ]射线，因此无法清楚地描绘出[α]粒子单独的生物效应。钋-210是氡衰变系列的终端放射性核素，可用于此目的，因为它具有相对较长的储存寿命（[tau][sub 1/2] = 138 d），并且在衰变为稳定的[sup 206]Pb时仅发射单个5.3 MeV [alpha]粒子。因此，它已被广泛用于放射生物学研究与纳入放射性核素。放射性核素[sup 210]Po在反应堆中由[sup 209]Bi产生。（作者）。
Over the last several years considerable concern has been expressed regarding the potential detrimental effects of radon and radon progeny on our health. The complex nature of the radon decay scheme, which involves the emission of a variety of radiations including several [alpha] particles, [beta] particles, and [gamma]-rays, does not lend itself to clear delineation of the biological effects of the [alpha] particles alone. Polonium-210, the terminal radionuclide of the radon decay series, is useful for this purpose because it has a relatively long shelf-life ([tau][sub 1/2] = 138 d), and it only emits a single 5.3 MeV [alpha] particle in its decay to stable [sup 206]Pb. Accordingly, it has been used extensively in radiobiological studies with incorporated radionuclides. The radionuclide [sup 210]Po is produced in a reactor from [sup 209]Bi. (Author).
