Radon exhalation from Libyan soil samples measured with the SSNTD technique

Radon concentrations in soil samples collected from the cities of Benghazi and Al-Marj, located in northeastern Libya, were measured using the sealed-can technique based on the CR-39 SSNTDs. Mass and areal radon exhalation rates, radium content and radon concentration contribute to indoor radon, and annual effective doses were determined. The results indicate mostly normal rates, but there were some higher levels of radon concentration and emanation in samples collected from Al-Marj and one sample from Benghazi.

► Radon exhalation was measured in Libyan soil samples by the SSNTD technique.
► The results indicate mostly normal levels of radon concentration.
► The mean radon concentration is 220.3±7.4 and 325.5±10.9 Bq m−3 for Benghazi and Al-Marj cities, respectively.
► We evaluated radon exhalation rates, the radium content and annual effective doses.
