Abstract

A simple ²²²Rn/²²⁰Rn exposure chamber is described. The chamber is made of acrylic and has a volume of 0.41 m³. The ²²²Rn and ²²⁰Rn sources can be operated independently or simultaneously. The concentrations of ²²²Rn and ²²⁰Rn were monitored by a continuous alpha spectrometer called RAD7. The capability of alpha spectrometry has removed the mutual interference between ²²⁰Rn and ²²²Rn, which is a major problem in measuring ²²⁰Rn. Furthermore, the capability can also provide fast response to changes in the ²²²Rn level and ²²⁰Rn level in the exposure chamber, with temporal resolutions of about 20 and 2min, respectively. © 2002 Elsevier Science B.V.
