Assessment of Radiological Hazards in Soil, Water and Plants Around Coal Power Plant

The existence of a Coal - Fired Power Plant (CFPP) is suspected to affect the environment quality, especially increment natural radionuclides content which found in coal as raw material. Therefore, systematic analysis ( 210 Pb, 234 Th, 238 U, 228 RA, 40 K, 226 RA and 232 Th) water, soil , plant were conducted establish data base o f environmental contamination area around CFPP. This research was Adipala Cilacap CFPP operates with two towers.
