Characteristics of Po in Asian overbite clam (Potamocorbula laevis) from the coastal area at Thai Binh province, Vietnam.

Po concentration in the edible muscle tissue and digestive diverticulum organs of Asian overbite clam at the near-shore Thai Binh, Vietnam was analyzed using alpha detectors. The Po activity in muscle tissue and digestive diverticulum organs ranged from 5 ± 1 to 178 ± 10 and from 118 ± 7 to 812 ± 12 Bq.kg with the average value of 25 and 324 Bq.

Radiological risk assessment of outdoorRn andRn around rare earth element and uranium mines from northern Vietnam.

The outdoorRn andRn concentrations at 320 sampling points at 1 m above the ground in different sites surrounding rare earth element (REE) and uranium mines from northern Vietnam were measured using the RAD7. Results showed thatRn concentrations were always higher thanRn concentrations with large variation ranges from 25.7 to 573 Bq mand from 18.
