Figure 5. CR wo-water values — species variation Adult frog CR wo-water values for species with sufficiently high sample numbers i. CR wo-water values — lake vs river Data for radiocaesium transfer to adult frogs were available for both lakes and rivers, presenting an opportunity to test whether there was a significant difference in the transfer between these two types of freshwater system. Table 3 A comparison of estimated absorbed dose rates to different life-stages of Montane Brown and Wrinkled frogs for Lake Akimoto in and Table 4 A comparison of absorbed dose rates to different life-stages of Montane Brown frogs for Uda River in and Discussion The similarity in CR wo-water values for Cs and Cs provides further evidence to support the commonly used approach 2 , 3 , 12 , 13 of treating isotopes of a given element as having the same CR wo-water value if the isotopes can be assumed to be in equilibrium.

Materials and Method We have extracted data from MOE Ministry of the Environment 10 for the eight freshwater systems for samples collected between June and June ; the data included radiocaesium activity concentrations in water, sediment and biota. Estimation of dose rates Dose rates have been estimated for the Wrinkled frog and Montane Brown frog given they have somewhat different life-histories and are examples of a species with a comparatively low and high CR wo-water values respectively.
