Correction: Evaluation of Risk Perception and Risk-Comparison Information Regarding Dietary Radionuclides after the 2011 Fukushima Nuclear Power Plant Accident

There is an error in Table 3. In row 10, the explanation incorrectly lists the unit of “1000 to 2000 mSv/year.” It should read “1000 to 2000 mSv.” Please see the corrected table here.

Table 3. Risk-comparison information provided, and its explanation.

“+” represents risk-comparison information used in this study.

Risk comparison information	Explanation	Covello's guideline	A	B	C
1. Radiation dose only (no comparison information)	–	-	+	+	+
2. Food standard dose	"Current standards for restrictions on the distribution of foods have been established from 1 mSv/y." a	1	+
3. Results for 100-mSv	"Clear health effects below 100 mSv have not been observed through epidemiology so far."	1	+
4. 1960s dose	"The average dose of dietary radiocesium in 1964 in Japan derived from nuclear bomb tests was 0.019 mSv/yea."a	1	+
5. Doses in other prefectures	Current doses in two other prefectures were provided.b	2	+
6. Natural radiation dose	"The natural radiation dose in Japan, excluding radiation from the 2011 accident, is 2.1 mSv/year (1 mSv/year from the diet; 1.1 mSv /year from other sources)."a	3	+
7. Total cancer mortality rate	"Approximately 20% of Japanese die from cancer."c	3		+
8. Airplane dose	"The dose from a round-trip between Tokyo and New York by airplane is approximately 0.2 mSv."	4	+
9. Arsenic risk	"The cancer risk from inorganic arsenic in rice and hijiki seaweed corresponds to approximately 0.2 mSv/year, if converted to radiation dose units."a	4	+	+
10. Smoking risk	"The cancer risk from smoking corresponds to approximately 1000 to 2000 mSv, if converted to radiation dose units."	5	+	+	+
