已经开发出一种用于大气 (222)Rn 的双过滤器连续监测器。其特点包括优于 0.01 pCi/l 的灵敏度、对 (222)Rn 的高特异性以及立即启动能力。该监视器经过计算机建模，以便于校准和选择操作参数。过滤器是固定的，不需要移动部件进行控制。现场试验表明可靠性高，并且可免维护运行一周或更长时间。
A two-filter, continuous monitor has been developed for atmospheric (222)Rn. Features include a sensitivity of better than 0.01 pCi/l, a high specificity for (222)Rn, and immediate start up capability. The monitor has been computer modeled to facilitate calibration and selection of operating parameters. The filters are stationary and require no moving parts for control. Field trials indicate high reliability and maintenance-free operation for periods of a week and longer.
