Radioactively Contaminated Dried Mushroom

8.1. According to current risk assessment result, is there any health effects from consuming the contaminated dried mushroom?

Based on the result of risk assessment conducted on 2 August 2013 regarding the contaminated dried mushroom sample, the radiation doses received by average and high consumers due to prolonged consumption (1 year) of the contaminated dried mushroom were approximately 0.0012 mSv and 0.0045 mSv respectively. For average consumer, the dosage is equal to the radiation dose received from about 1/50 chest X-ray examination or 1/5000 CT scan, or 1/50 the radiation dose received from air travel for a round trip from Hong Kong to the West Coast of the United States. For high consumer, the dosage is equal to the radiation dose received from about 1/11 chest X-ray examination or 1/1667 CT scan, or 1/17 the radiation dose received from air travel for a round trip from Hong Kong the West Coast of the United States. In other words, adverse health effects due to the internal dose from the concerned dried mushroom sample alone by both the average and high consumers are unlikely.
