“…Root absorption depends on soil properties such as pH, mineral composition, organic matter content, and nutritional status as well as metabolic and physiological characteristics of plant species [12,33]. The uptake of radionuclides into cassava leaves and grass is one of the many factors for the migration of natural radionuclides to human from the environment through the food chain [34,35].…”

The existence of a Coal-Fired Power Plant (CFPP) is suspected to affect the environment quality, especially the increment of natural radionuclides content which is found in coal as raw material. Therefore, systematic analysis of natural radionuclides ( 210 Pb, 234 Th, 238 U, 228 RA, 40 K, 226 RA and 232 Th) in water, soil, and plant were conducted to establish a database of environmental contamination in the area around a CFPP. This research was conducted in the area around Adipala Cilacap CFPP which operates with two towers. Samples were taken from three locations around the Adipala CFPP based on the secondary wind direction data from Indonesian Agency for Meteorological, Climatological, and Geophysics in the 2018 dry season. Samples were prepared in the Radiochemistry Laboratory, Center for Accelerator Science and Technology, BATAN. The concentration of radioactivity in environmental samples were analyzed using gamma spectrometry with a high purity germanium detector for 24hours after reaching its secular equilibrium. The result of samples analyses shown that the mean value of the radionuclides specific activities ( 210 Pb, 234 Th, 238 U, 228 RA, 40 K, 226 RA and 232 Th) for water, cassava leaves, grass, and soil were 0.789 Bq/L, 14.685 Bg/kg, 15.036 Bq/Kg, and 75.083 Bq/kg, respectively. The mean of radium equivalent activity (Ra eq ) for water, cassava leaves, grass, and soil were 1. 692, 30.792, 18.699 and 137.513 Bq/kg, respectively. The absorbed dose rate (ADR) for water, cassava leaves, grass, and soil were 0.775, 14.332, 8.627, and 64.135 nGy/h, respectively, whilst the annual effective dose rate (AEDR) were 0.004, 0.070, 0.042, and 0.315 mSv/y. The mean of external and internal hazard indices (H ex and H in ) for water, cassava leaves, grass, and soil were 0.005 and 0.006, 0.083 and 0.129, 0.050 and 0.078, and 0.371 and 0.554, respectively, while the mean of excess lifetime cancer risk (ELCR) wre 0.014×10 -6 , 0.246×10 -6 , 0.148×10 -6 , and 1.101×10 -6 . According to the calculation of radiation hazard index in this research, it was understood that all parameters of all samples were within acceptable limits by the world average value reported by the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR).

“…Naturally occurring materials generally contain radioactive nuclides from the main decay chains for 238 U, 235 U, 232 Th, and their daughter products, and from the long-lived radioactive nuclides such as 40 K [ 15 ]. However, the occurrence of anthropogenic (artificial) radioactivity and technologically enhanced natural radioactivity causes the alteration of the natural ecological characteristics of the biosphere [ 16 ]. The commonly encountered radionuclides include 232 Th, 239 Pu, 226 Ra, 60 Co, 222 Rd, 99 Tc, and 238 U [ 17 ].…”

“…When the results obtained were compared with recommended limit (RL), it was observed that more doses are ingested from the consumption of Catfish compared to Tilapia and the values of the effective doses increase in the order of adult < 15 years < 10 years < 5 years < fishermen. Nevertheless, each and every one of these values were quite low compared to the mean world value of 1000 µSvy −1 and hence pose no serious radiation hazard [22,[27][28][29][30][31], but it is recommended that Tilapia should be consumed instead of Catfish in cases of long-term radiation injury.…”

High concentration of naturally occurring radionuclides in food can have adverse effect on human health. Radioactivity measurement of radionuclides in Catfish and Tilapia fish samples from Asa-Dam Ilorin, Nigeria was carried out using gamma ray spectrometer technique. The results of the gamma ray spectrometry were utilized in the estimation of some radiological parameters in the bid to effectively determine the extent of the health implications as regards to radiation from the consumption of fishes in that area. The mean activity concentrations of 40K, 238U and 232Th for Catfish are 37.90±2.83, 8.08±2.71 and 11.73±2.51 Bqkg-1, respectively. Similarly, the mean activity concentrations of 40K, 238U and 232Th for Tilapia are 26.31±3.67, 6.16±2.47 and 8.89±2.19 Bqkg-1, respectively. The mean values of 40K, 232Th and 238U in Catfish were observed to be high when compared to Tilapia. The average absorbed dose rate for both Catfish and Tilapia samples were 12.40 and 9.31 nGyh-1. The mean annual effective doses were 29.65, 276.81, 52.04, 41.10 and 35.00 μSvy-1; 22.41, 209.10, 38.99, 30.93 and 26.43 μSvy-1 for adult, fishermen, 5 years, 10 years and 15 years, respectively for cat and Tilapia fish. The estimated excess lifetime cancer risk for adult, fishermen, 5 years, 10 years and 15 years were 0.10, 0.97, 0.18, 0.14, and 0.12 and 0.09, 0.85, 0.16, 0.13 and 0.11 for both Catfish and Tilapia, respectively. The results of all the radiological parameters estimated showed trends that are generally low, hence, poses no significant radiological health burden.
