Abstract: Researcher of the consequences of the Chernobyl disaster Kiyohiko Mabuchi (US National Cancer institute) says, there might be little increase of carcinoma among liquidators of Fukushima. Comparing Fukushima to Chernobyl, the exposure dose in Japan is much lower than the latter.

Abstract: Long-term investigations of radiocaesium activity concentrations in carp in the Republic of Croatia are presented. The radiocaesium levels in carp decreased exponentially and the effective ecological half-life of 137Cs was estimated to be about 1 year during 1987–2002 and 5 years during 1993–2005.
The observed 134Cs:137Cs activity ratio in carp was found to be similar to the ratio observed in other environmental samples.
The concentration factor for carp (wet weight) was estimated to be 128 ± 74 L kg−1, which is in reasonable agreement with model prediction based on K+ concentrations in water.
Estimated annual effective dose received by adult members of the Croatian population due to consumption of carp contaminated with 134Cs and 137Cs are small: per capita dose from this source during 1987–2005 was estimated to be 0.5 ± 0.2 μSv.
Due to minor freshwater fish consumption in Croatia and low radiocaesium activity concentrations in carp, it can be concluded that carp consumption was not a critical pathway for the transfer of radiocaesium from fallout to humans after the Chernobyl accident.
