Adsorptive and desorptive data are presented for 20 activated charcoal (AC) types that may be used in passive 222Rn sampling devices. Open-faced AC canisters were exposed for 3 d at room temperature to known radon and water vapor concentrations. Gamma measurements of radon progeny activity show that the optimum radon-adsorbing ACs are Calgon-PCB, Norit (RI, RBI, or PK), and, to a lesser degree, Witco-965 and ENV-EI-1220.
给出了20种可用于被动式氡-222采样装置的活性炭(AC)的吸附和解吸数据。将敞口式活性炭罐在室温下暴露于已知的氡和水蒸气浓度中3天。氡子体活度的伽马测量结果表明,最佳的氡吸附活性炭是卡尔冈-多氯联苯、椰壳活性炭(RI、RBI或PK),以及在较小程度上的威特科-965和ENV-EI-1220。
