Adsorption and volatility of free 211At and 125I-.
The present study was undertaken to extend our knowledge of the behaviour of 211At in the laboratory environment. An unexpectedly high volatility of free 211At was found, up to 85% during an hour. Free 211At also adsorbed more onto the plastic material studied than 125I-. The results of this study show that it is of great importance to pay careful attention to radiation protection procedures during the practical handling of free 211At.
