    Notizen: 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.

    Notizen: Abstract Tritium concentrations were measured for river waters on two islands in Japan. Significant difference was observed on the distribution of tritium concentrations on both islands, the river water samples from the northern island had higher concentrations and the average was about twice compared to that from the southern island. Higher tritium concentration in precipitation and the larger area of the northern island would be responsible for higher tritium concentrations in river waters.
