Abstract
1 Scope This document specifies a method for the determination of the free radon exhalation rate of a batch of mineral based building materials . This document only refers to 222 Rn exhalation determination using two test methods: liquid Scintillation Counting (LSC) and gamma ray spectrometry (see Annex A and Annex B). The exhalation of thoron ( 220 Rn) does not affect the test result when applying the determination methods described in this document.
