Abstract

Uranium and radium isotopes were measured in 17 water samples (6 thermal, 3 stream and 8 commercial bottled waters) using LSC and alpha spectrometer after chemical separation. The thermal and stream water samples were collected from Kim Boi spa Hoa Binh, North Vietnam. The measured radioactivity ranged ≤ 0.5 ÷ 9.0 mBq/L for 238U, 1.60 ÷ 18.6 mBq/L for 234U, ≤ 5 ÷ 29.2 mBq/L for 226Ra. For the bottled water 234U was ≤ 3 mBq/L and 238U undetected, the 226Ra ranged 5 ÷ 202 mBq/L and 228Ra ≤ 20 ÷ 115 mBq/L. For studied thermal water the increasing tendency of Ra concentration with depth water formation is observed.
