We utilized autoradiography to visualize radioactive contamination in the skeletal muscles of a pig raised within 20 km of the Fukushima Daiichi nuclear power plant following the nuclear accident. The autoradiogram of control muscle showed relatively homogenous exposure. In contrast, the autoradiogram of affected muscle showed a heterogeneous and sporadically dense imaging pattern.
The present study focused on a mixed-breed male pig that was born and raised on a farm within 20 km of the Fukushima Daiichi nuclear power plant. The pig was moved to an uncontaminated area 17 days after the accident (March 29, 2011), and it was slaughtered 41 days later (May 10, 2011). Another male pig was raised in an uncontaminated area and slaughtered on the same day as a control. Skeletal muscle (ham, 100 g) from each pig was sampled in a polystyrene container for radionuclide detection.
The muscle of the affected pig was contaminated with 40K [naturally-occurring potassium-40], 134Cs, and 137Cs at levels of 110.3, 48.2, and 67.9 Bq/kg, respectively (measured on the day of ARG exposure). This pig had been fed complete imported feed before movement, so the internal contamination might be led by intake of contaminated water or inhalation of contaminated air. The control pig contained only 40K, which was detected at a level of 123.2 Bq/kg.
