Abstract As a screening procedure, gross alpha and gross beta activity have been developed to determine whether further analysis of water samples related to specific radionuclide is necessary. In China, the determination of gross alpha and gross beta in drinking water was generally based on the HJ standard method: HJ 898-2017, water quality — determination of gross alpha activity — thick source method, and HJ 899-2017, water quality — determination of gross beta activity — thick source method. In this study, 15 water samples from Bahe river in Chan Ba region of Xi’an in China, were pretreated and analyzed by BH1216-III low background alpha and beta scintillation counter. The water samples were collected nearby residential area, wetland park, water conservation district and urban sewage treatment plant as well as other important locations which probably influence on the radioactivity level. The values of the activity concentrations of the gross alpha and beta measured in the water samples ranged from less than LD to 0.183Bq/L with a mean of 0.077Bq/L and 0.073–0.151Bq/L with a mean 0.102Bq/L respectively. All values of samples were lower than the limit level of 0.500Bq/L for gross alpha and 1.000Bq/L for gross beta, indicating that the radioactivity level in Bahe water between Chan Ba region of Xi’an is basically within the normal environmental background.

This study was conducted for natural radioactivity of some fish feed samples in Nigeria, using gross alpha and beta method with protean instrument corporate (PIC) MPC 2000DP detector. The range of the gross alpha concentration for the sample, for the Uranium series was 0.0246 ± 0.0051 Bq/g to 0.0028 ± 0.0055 Bq/g, similarly for gross beta concentration ranges from 0.0651 ± 0.0104 Bq/g to 0.0621 ± 0.0100 Bq/g for the samples. The annual effective doses of the activities for the three sample A, B, and C which were 18.56 μSvy-1, 10.91 μSvy-1 and 17.20 μSvy-1 respectively. The results appeared to be below the standard annual effective dose of 70 μSvy-1 for humans as recommended by (UNSCEAR, 1977 and 1982). This research shows that consumers of fish have no risk of radioactivity ingestion in to the food chain, even though no amount of radiation is assumed to be totally safe because radiation is known to trigger or induce cancer

Concentration of trace elements and natural gross radioactivity were measured in the drinking water in Jizan region (Saudi Arabia). A preliminary study on trace elements (Zn, Fe, Mn, Ni, Cu, Cr, Co, Se, Sr, V, Ti, Mo, Hg, Cd, Ba, As, Al and Pb) concentrations and natural radioactivity related to gross-α and gross-β radiations in the drinking water were determined. The obtained results showed that, in general, the trace elements concentrations in water did not exceed WHO [1], and GSO [2] guidelines. Generally, heavy metals concentration of the drinking water were found to be in the sequence of Sr > Ti > Fe > Al > Zn > Ba > As > Cu > Mo > Ni > Cr > Co > Se >Hg > Mn, respectively. The results of this study indicated that a general absence of serious pollution in the drinking water used in this region. The results obtained from the radioactivity determination indicate that the drinking water radioactivity concentration of gross-α and gross-β were ranging from 0.06±0.001 to 0.45±0.03 Bq/l and from 0.05±0.006 to 2.95±0.23 Bq/l, respectively. The gross alpha values were found to fall below the GSO and WHO recommended MCL of 0.5 Bq/l while the gross beta values in two samples only exceeds the MCL value of 1 Bq/l, respectively.
