Abstract

In this work the concentration levels of ²²⁶Ra were measured in 42 samples related to 14 types of bottled natural mineral water commercially available in market. The applied method for this measurement was emanation method with a minimum detection limit of 2 mBq l^-1. After adjusting the pH below 2 by concentrated HCl, the radium was co-precipitated with barium and lead as sulfate. The precipitate was dissolved in alkaline EDTA (C₁₀H₁₄N₂O₈.2H₂O) and placed in 20ml bubbler. The bubbler was sealed and stored for 21 days at 5^oC for ingrowth of ²²²Rn. For calculation the committed effective dose for adults drinking 40 l y^-1 of bottled mineral water, the ingestion dose conversion coefficients from the IAEA publications is used. Concentration of ²²⁶Ra ranged from 2.0 to 12.3 mBq l^-1. In one case 12.3 mBq l^-1 was measured, which provides 0.138 µSv committed effective dose for adults in the case of consumption rate of 40 l y^-1.
