Abstract

Loss of⁹⁹Tc in seaweed during dry ashing has been investigated. Two kinds of brown seaweeds labeled with⁹⁹Tc were ashed for 24 or 48 h at 400, 450 and 500 °C, showing no correlation between the loss of⁹⁹Tc and species, temperature and time of ashing. The averaged recovery of⁹⁹Tc was 91.0±4.0%, indicating that most of the⁹⁹Tc in the seaweed was retained within the matrix of the ash which was obtained under general conditions of ashing.
