在这项研究中，从2003年到2008年，使用被动氡和钍射气测量装置（Radopot（（R））和Raduet（（R）调查了匈牙利的几个住宅和工作场所。在1至3个月的时间内，将探测器放置在距离墙壁15-30 cm处。在住宅中，几乎在所有情况下都检测到类似于100 Bq m（-3）的钍射气的存在;然而，在这些建筑物的地窖中，类似于200 Bq m（-3）的值是典型的。在锰矿和铝土矿的情况下，钍射气的浓度主要分别为200和500 Bq m（-3）。在洞穴中，它是1000 Bq m（-3），而在氡浴中，它类似于100 Bq m（-3）。在许多情况下，钍射气和氡浓度之比> 0.25，来自钍射气及其子体的剂量贡献不可忽略。因此，对钍射子体的进一步研究对于准确的剂量估算是必要的。
In this study, several Hungarian dwellings and working places were surveyed using passive radon- and thoron-measuring devices (Radopot((R)) and Raduet((R))) from 2003 to 2008. The detectors were placed 15-30 cm from the wall throughout the 1- to 3-month period. In dwellings, the presence of thoron, similar to 100 Bq m(-3), was detected almost in all cases, ; however, in the cellars of these buildings, a value similar to 200 Bq m(-3) was typical. In the cases of manganese and bauxite mines, the concentration of thoron was mainly 200 and 500 Bq m(-3), respectively. In caves, it was 1000 Bq m(-3), whereas in the radon bath it was similar to 100 Bq m(-3). As in many cases, the ratio between thoron and radon concentrations was > 0.25 and the dose contribution from thoron and its progeny was not negligible. Therefore, further investigation on the thoron progeny will be necessary for an accurate dose estimation.
