Abstract
Activity concentrations of primordial radionuclides such as 40K, 226Ra and 232Th were determined in edible mushrooms samples in Ekiti State Nigeria. The edible mushrooms collected are Termitomyces striatus, Psathyrella atroumbonata, Termitomyces robustus, Pleurotus tuber-regium and Pleurotus squarrosulus. The activity measurements were carried out by gamma spectrometry. The average concentrations of 40K varied from 254.17 ± 46.78 to 416.07 ± 68.43 Bq·kg-1, 226Ra concentrations varied from 2.68 ± 0.82 to 21.64 ± 7.23 Bq·kg-1 and 232Th concentrations varied from 8.57 ± 3.25 to 10.98 ± 4.31 Bq·kg-1. The concentrations were converted to effective dose. Effective doses calculated were found to be below maximum permissible levels. Therefore, no health risk is envisaged for those that normally consumed these mushrooms.
Highlights
Anthropogenic (90Sr, 137Cs and 134Cs) and primordial (40K, 226Ra and 232Th) radionuclides are available in diverse environments such oceans, rivers, streams, soils, rocks, vegetable, animals and human body [1]
Mushrooms are highly rich in fiber, proteins, vitamins and minerals such as potassium, phosphorus, iron and sodium and are widely consumed in Ekiti State
Edible mushrooms were obtained from different towns and villages in the state
Summary
Anthropogenic (90Sr, 137Cs and 134Cs) and primordial (40K, 226Ra and 232Th) radionuclides are available in diverse environments such oceans, rivers, streams, soils, rocks, vegetable, animals and human body [1]. Radioactivity measurements in food stuffs (especially mushrooms) have widely reported in literature [3]-[11].
