“…Although the highest concentration of 210 Po occurs in marine biota organs (eg liver) which are involved in digestion and metabolism. The same applies to the dose rate because it is proportional to the concentration of 210 Po activity in the body of marine biota [4]. The fatal dose limit for consuming 210 Po is 3.75 MBq, which is equivalent to 21 ng 210 Po with an effective dose coefficient of 1.2 x 10-6 Sv Bq -1 .…”

“…210 Po accumulates in high concentrations in a variety of marine organisms, so 210 Po is responsible for most of the absorbed dose humans receive from ingestion of seafood. Additional sources of 210 Po to the marine environment can occur from the discharge of industrial activities such as the phosphate industry, mining and milling, also oil and gas extraction [4]. 210 Po is a high energy alpha-emitting radioisotope (5.3 MeV) that the most radiotoxic activity and accumulation efficiency in fish soft tissues.…”

“…Research on 210 Po has been widely carried out in various countries [3,4,6]. Hansen (2022) as an example: determination of 210 Po content in macroalgae, molluscs, crustaceans, fish, to mammals [4]. According to Musthafa (2019), the activity concentration of 210 Po increased in the following order of bladderwrack, shrimp, and mussels and from fish species to seals and polar bears [3].…”

“…The process of controlling the bioaccumulation of 210 Po is complex and many factors are involved in controlling the uptake behavior of fish [21]. Compared to the annual dose in Greenland conducted by Hansen (2022), the average annual effective commitment dose of 210 Po through the consumption of seafood and marine mammals for adults is 771 ± 89 (μSv), and for children (5 years) is 1410 ± 326 (μSv) [4]. The annual effective dose may differ depending on the concentration of 210 Po in seafood and the level of the annual consumption of that seafood.…”

The measured of 210Po concentration in the commercially fish muscle has been conducted in fish species collected in southern coast of Sukabumi in 2021. 210Po is a natural occurring radionuclide from the 238U series in the environment and become a concern due to radiotoxic effect for the health of consumers. This study aims to determine the concentration activity of 210Po and to evaluate the annual effective dose of 210Po on fishery products in southern coast Sukabumi. There were ten different species of marine fish were analyzed using an alpha spectrometer. The results showed that the highest concentration of 210Po activity was in a common dolphinfish at 13.57 ± 2.03 Bq Kg−1 dry weight. This activity value was exceeded tolerable limits as reported by the global recommended concentration of 210Po for fish was about 2.4 Bq Kg−1. The lowest concentration of 210Po was found in Pink ear emperor fish at 0.18 ± 0.10 Bq Kg−1 of dry weight, which below minimum threshold of limit concentration activity. The results of the investigation that the average effective dose from one year fish consumption in Sukabumi for adult consumers ranged from 1.05-112 (µSv/a), children (10 years) ranged from 2.27 – 243 (µSv/a), and infant consumers (1 year) ranged from 7.67 – 821 (µSv/a). The annual dose from 210Po intake in the recent study are lower from reference level of 1 mSv, therefore 210Po was not become a concern.
