Determination of radionuclides’ activity concentration in fruits is essential for the protection of human health. Fruits can be radioactive due to the present of naturally occurring radioactive materials (NORMs) and technically enhanced radioactive materials (TENORMs) in the environment. The Assessment of Radionuclide activity concentration in Some Fruits from Niger Delta, Nigeria and its Health Risks were carried out using gamma ray spectroscopy. The study measured the activity concentration of radionuclides in fruits and the results showed that the total activity concentration of 40K, 232Th and 226Ra in fruits were 578.24 Bqkg-1, 263.84 Bqkg-1 and 128.35 Bqkg-1 respectively. The study found out that 40K has the highest value of activity concentration while apricot has the highest value of radionuclide concentration compared to other fruits. The statistical analysis of data was also done using statistical packages. The average estimated AED for Infants, Children and Adults due to the radioactivity in Avocado, Apricot, Guava and Pear were; 829.02 µSvy-1, 565.865 µSvy-1, and 838.725 µSvy-1, 2737.665 µSvy-1, 4361.4875 µSvy-1 and 2497.9025 µSvy-1, 651.20833 µSvy-1, 1202.6767 µSvy-1 and 813.22167 µSvy-1, and 1164.7883 µSvy-1, 1724.2933 µSvy-1 and 1088.8933 µSvy-1 respectively. The estimated AED due to the consumption of various fruits are above the world value. However, the estimated excess lifetime cancer risks for the various fruits are far below the world (WHO) limit. The study concluded that there is no cancer risk associated with the consumption of fruits in the study area and that the fruits that have tap root systems recorded highest value of radionuclides’ activity concentration.

“…This matter has become a great concern as has been reported by many researchers in different part of the world. From eleven different countries, 58 types of vegetables have been studied with seven common types namely spinach, carrot, cucumber, tomato, pumpkin, green bean and potato [6][7][8][9][10][11][12][13][14][15][16]. However in Malaysia, only 16 types of vegetables have been studied with spinach and cucumber as the common type [17,18].…”

The activity concentration of natural radionuclides 226 Ra, 232 Th and 40 K 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 -4 respectively for adults. The results obtained for activity concentration, dose and risk were found to be below the internationally recommended level. This indicates that the vegetables and fruits consumed in Malaysia would not pose any significant radiological impact to the population.Keywords: activity concentration, gamma spectrometry, ingestion dose, natural radionuclides, risk assesment Abstrak Kepekatan aktiviti radionuklid semulajadi 226 Ra, 232 Th and 40 K dalam sayur-sayuran dan buah-buahan di Malaysia bahagian tengah telah diukur menggunakan spektrometer gama. Ini bertujuan untuk menilai risiko radiologi dalam istilah dos dimakan dan risiko kanser. Didapati jumlah dos dimakan dari pengambilan sayur-sayuran adalah 0.469 ± 0.003, 0.326 ± 0.005 and 0.232 ± 0.003 mSv/tahun masing-masing bagi bayi, kanak-kanak dan dewasa. Manakala jumlah dos dimakan dari pengambilan buahbuahan bagi bayi, kanak-kanak dan dewasa adalah masing-masing 0.349 ± 0.005, 0.283 ± 0.007 and 0.195 ± 0.004mSv/tahun. Risiko kanser dari pengambilan sayur-sayuran dan buah-buahan bagi orang dewasa masing-masing dijangkakan sebanyak 8.13 × 10 -4 dan 6.83 × 10 -4 . Kesemua hasil yang diperolehi dalam kajian ini bagi kepekatan aktiviti, dos dan risiko didapati berada di bawah aras yang dibenarkan oleh badan antarabangsa. Ini menunjukkan bahawa sayur-sayuran dan buah-buahan yang diambil di Malaysia tidak menimbulkan bahaya radiologi yang ketara terhadap manusia.Kata kunci: kepekatan aktiviti, spektrometer gama, dos dimakan, radionuklid semula jadi, penilaian risiko IntroductionThe total annual radiation dose received by a member of the population each year is 3.01 mSv. About 79.73% of this number is contributed by natural radiation sources (2.4 mSv/y) and the rest 20.27% by man-made radiation sources (0.61 mSv/y) [1]. It is clear that the natural radiation sources is the main contributor to the total annual radiation dose. One component of this natural radiation sources is the ingestion dose (0.29 mSv/y) that are mainly contributed by

“…Whereas for category \1 and 12-17 years, the largest contributor is 226 Ra (44 and 53 % respectively) followed by 40 K and 232 Th. The large number of 40 K is not surprising as it is an essential element and being homeostatically controlled in the human body [2,30]. But different case happens with 226 Ra, where it can be absorbed into the blood stream and distributed to soft tissue and bones [31].…”

The activity concentration of 226 Ra, 232 Th and 40 K were determined by gamma spectrometry in twenty-six different brands of powdered milk available in Malaysia. The measured activity concentration was then used to estimate the radiation hazard indices in term of ingestion dose and cancer risk. The total ingestion dose was found to range between 35.19 and 461.72 lSv y -1 and the estimated cancer risk for adult is 1.23 9 10 -4 . These results were found to be below the internationally recommended level. This indicates that the powdered milk in Malaysia would not pose any significant radiological impact to the population.
