Zusammenfassung: | Natural Radionuclides are elements that are found in the air, water and
soil. They find their ways in to the plants through the leaves and
absorption of nutrients and water from the soil through the roots.
Intake of fruits is very essential for human beings as part of balance
diet. The concentrations of natural radionuclides in some fruits from
three major markets at Ijebu- Ode town in Nigeria were determined and
annual committed effective dose to the consumers was also determined.
The gamma spectrometry method was used for the analysis. The highest
concentrations of 40K, 238U and 232Th were from pineapple of value
102.36 ± 10.81Bqkg-1, orange of value 12.18 ± 4.36Bqkg-1 and
mango of value 8.01 ± 3.25 Bqkg-1 respectively. The average annual
committed effective dose of the natural radionuclides to the consumers
was calculated to be 0.11mSvyr-1, which is below the limit of
0.3mSvyr-1 recommended globally. This indicates that the ingestion of
these radionuclides through the consumption of these fruits has no
radiological health hazard to the consumers. |
