Abstract

The activities concentration of 226Ra and 228Ra in marine biota at Kapar coastal area nearby Sultan Salahudin Abdul Aziz Shah Power Station (SJSSAAS) had been analyzed. The techniques that had been used to determine the activities concentration of 226Ra dan 228Ra are radiocnhemistry procedures and liquid scintillation counter (LSC). Results shows that the distribution of radium isotopes depend on the location and during sampling periods. The activities concentration of 226Rai and 228Rai in tissue were ranged 11.82 ± 5.23 Bq/kg -17.67 ± 6.81 Bq/kg and 40.42 ± 16.20 Bq/kg -67.86 ± 23.11 Bq/kg, respectively. The mean activities concentration of radium isotopes in bivalvia such as cockles (anadara granosa) are 61.73 ± 24.15 Bq/kg (226Raag) and 232.62 ± 119.44 Bq/kg (228Raag). Meanwhile for green mussles (perna viridis), the mean activities concentration of 226Rapv dan 228Rapv are 38.24 ± 14.19 Bq/kg dan 99.59 ± 44.91 Bq/kg, respectively. Concentration Factor (CF) in marine biota is higher than 1 × 104 and it is because of the accumulated radium isotopes is low and has a high affinity for organic matter. The study also shows the effectiveness of dose in radium isotopes were measured to ensure the safety of users and it is still below the limit allowed Malaysia which is 1 mSv / year.
