Radiological risk assessment from the intake of vegetables and fruits in Malaysia. Malaysian Journal of Analytical Sciences, 20 (6). pp. 1247-1253. ISSN 1394-2506 (2016)
Abstract
The activity concentration of natural radionuclides 226Ra, 232Th and 40K in vegetables and fruits in central zone of Malaysia were measured using gamma spectrometry. This is for the purpose of assessing the radiological risk in term of ingestion dose and cancer risk. The total ingestion dose from the consumption of vegetables were found to be 0.469 ± 0.003, 0.326 ± 0.005 and 0.232 ± 0.003 mSv/y for infants, children and adults respectively. Whereas the total ingestion dose from the consumption of fruits for infants, children and adults were 0.349 ± 0.005, 0.283 ± 0.007 and 0.195 ± 0.004 mSv/y respectively. The estimated cancer risk from the consumption of vegetables and fruits were 8.13 × 10-4
and 6.83 × 10-4respectively for adults. The results
obtained for activity concentration, dose and risk were found to be below the internationally recommended level. This indicatesthat the vegetables and fruits consumed in Malaysia would not pose any significant radiological impact to the population.
