Abstract

Presently bottled sweet drinks are widely consumed by different age groups of individuals all over the world. Since bottling until consumption of sweet drinks, residual gas containing 222Rn and 220Rn isotopes is formed. To assessradiation dose to the consumers from the ingestion of sweet drinks, 222Rn and 220Rn concentrations were measured in different sweet drinks and their residual gases by using CR-39 and LR-115 type II solid state nuclear track detectors (SSNTDs). The measured 222Rn and 220Rn concentrations ranged from (0.3500.028) Bql-1 to (4.250.29) Bql-1 and (0.1400.008) Bql-1 to (4.250.38) Bql-1, respectively. α-activities due to the annual intake of 222Rn were assessed in the tissues and organs of the gastrointestinal tract of the considered consumers. Committed effective doses due to the ingestion of 222Rn contained in each sweet drink and its corresponding residual gas were evaluated in the gastrointestinal system of adult and teenager members of the Moroccan population. The maximum value of the committed effective dose due to 222Rn from the ingestion of the studied sweet drinks was found equal to7.9 µSv y-1.
