초록

In order to provide an effective preparedness for a nuclear or radiological emergencyhappening in the domestic or neighborhood countries and to solve the vague fear of the people forthe ingestion of radioactive livestock products, the establishment of national guideline level forradionuclides in feed is urgently necessary. This is because it is important to secure the safety andto manage the crisis in the agricultural, fishery and food sector by performing the effective safetycontrol during and after nuclear incident. This study was performed to investigate the report casesof international organizations and foreign countries to set up a domestic control standard formanaging radioactive substances that may be contaminated in animal feeds due to the nuclearpower plant incident. In addition, an attempt was made to provide a useful reference that can helpprepare a domestic control standard, using a coefficient that can consider the transfer into livestockthrough the intake of radioactive contaminated animal feeds. The standard radioisotopes investigatedwere confined to radioactive cesium (137+134Cs) and iodine (131I). Guideline level for theradionuclides was calculated by using the transfer coefficient factor and the maximum daily intakeof animal feed provided by IAEA. For example, the maximum daily intake of animal feed was setas 25 kg d-1 for dairy cows, 10 kg d-1 for beef cattle, 3.0 kg d-1 for pigs and 0.15 kg d-1 for chickens.
The result values for radioactive cesium were calculated as 8,696 Bq kg-1, 4,545 Bq kg-1, 1,667 Bqkg-1 and 2,469 Bq kg-1, respectively. The results for radioactive iodine showed the ranges between741 Bq kg-1 and 76,628 Bq kg-1. These data can be utilized as a scientific reference for the preparationof a crisis management manual for the emergency control due to nuclear power plant accidentin Korea and neighboring country. These results will contribute to establish the safe feedmanagement system at national level as manual for responding the radioactive exposure of agriculturalproducts and animal feeds, which are currently not established.
