Abstract

Abstract:

Objective: To examine the influence of the Japanese Fukushima nuclear accident on the activity concentrations
of ¹³⁴Cs and ¹³⁷Cs in import squid at Zhoushan ports. Methods: A total of 310 samples from the North Pacific Ocean, the Sea
of Japan, Argentina sea area, and Peru sea area were selected during 2011?2014, and the activity concentrations of ¹³⁷Cs and
¹³⁴Cs in these samples were analyzed by using a high-purity germanium (HPGe) gamma-ray spectrometer. Results: Among
310 samples analyzed, 20 (6.5%) were found to be positive and the North Pacific squid accounted for 85.0% of the total
positive samples. The highest specific activity values of ¹³⁷Cs and ¹³⁴Cs were 6.89 × 103 and 4.12 × 103 Bq/g, respectively, far
lower than the standard limits in different countries (the minimum limit is 100 × 103 Bq/g). Conclusion: The specific activity
values of ¹³⁷Cs and ¹³⁴Cs in import squid at Zhoushan ports were lower than 10.0 × 103 Bq/g, not harmful to food quality and
safety. However, the relative detection rates of squid from the North Pacific Ocean and the Sea of Japan squid were higher.
Thus, attention should be paid to this issue.
