| Abstract: | Coffee and green tea
drinks as well as sugar are widely consumed by Moroccan population. 238U,
232Th, 222Rn and 220Rn contents have been
measured inside different soil, sugar beet and table sugar material samples
collected in different areas of Morocco by using CR-39 and LR-115 type II solid
state nuclear track detectors (SSNTDs). The transfer of contents 238U,
232Th and 222Rn between soil and sugar beet and that
between sugar beet and table sugar has been measured. To explore the exposure
pathway of 238U, 232Th and 222Rn to the organs
and tissues of consumers from the ingestion of coffee and green tea drinks,
contents of these radionuclides have been measured in the drinks. The effect of
the nature water and pollution on the concentrations of these radionuclides in
coffee and green tea has been investigated. Annual committed effective doses
due to 238U, 232Th and 222Rn from the
ingestion of table sugar and coffee and green tea drinks by the members of the
general public and workers have been determined. The maximum total committed
effective dose due to 238U, 232Th and 222Rn
from the ingestion of tea drinks by the members of the Moroccan rural
population was found to be equal to 0.13 mSv y-1. |
