| Abstract:: |
| Objective To investigate the levels of gross alpha and gross beta radioactivity in different food groups in the diet of Fuzhou residents.Methods According to the food lists surveyed in the total diet study, 61 samples were collected from large and medium-sized supermarkets in Fuzhou, encompassing 11 categories of daily edible foods (cereals, potatoes, legumes, meat, eggs, milk, aquatic products, vegetables, fruits, alcohol and sugars). The samples were taken from edible parts and then ashed, and the gross alpha and gross beta radioactivity were measured by using low background alpha, beta counters.Results The average gross alpha activity concentrations were cereals 0.43 ± 0.55, potatoes 1.30 ± 0.65, legumes 0.79 ± 0.62, meat 0.17 ± 0.14, eggs 1.10 ± 0.64, milk 0.02 ± 0.01, aquatic products 5.70 ± 6.02, vegetables 0.45 ± 0.46, fruits 0.27 ± 0.25, alcohol 0.06 ± 0.02, and sugars (0.54 ± 0.28) Bq/kg. The average gross beta activity concentrations were cereals 33.40 ± 10.82, potatoes 87.00 ± 0.10, legumes 137.34 ± 179.30, meat 56.97 ± 24.55, eggs 80.50 ± 32.44, milk 24.40 ± 9.84, aquatic products 140.50 ± 101.32, vegetables 46.99 ± 22.80, fruits 43.74 ± 13.46, alcohol 7.59 ± 0.06 and sugars (1.12 ± 0.02)Bq/kg.Conclusions The radioactivity levels of gross alpha and gross beta in the diet of Fuzhou residents are still within the range of the previous surveys, without elevated levels of gross radioactivity. |
