title: 222RN and 220RN concentrations measured in various natural honey samples by using nuclear track detectors and resulting radiation doses to the members of the rural populations in Morocco.
abstract: Radon (222Rn) and thoron (220Rn) concentrations were measured in sixteen natural honey material samples collected from different regions in Morocco by using CR-39 and LR-115 type II solid state nuclear track detectors (SSNTDs). The concentrations of these radionuclides were also measured in nectar solutions corresponding to the studied honey samples. The measured concentrations of 222Rn and 220Rn in honey samples ranged from (2.3 +/- 0.2) to (8.1 +/- 0.6) Bq.l(-1) and (1.8 +/- 0.1) to (3.9 +/- 0.3) Bq.l(-1), respectively. Committed equivalent doses due to annual intakes of 222Rn were evaluated in the human gastrointestinal tract compartments of adult members of the Moroccan populations from the ingestion of studied honey samples. The influence of the target tissue mass and activities due to 222Rn on the annual committed equivalent doses in the compartments of the human gastrointestinal tract was investigated.
