Abstract:To investigate, the radiological hazards indices of chemical fertilisers commonly used in agriculture soils of Arasbaran, Iran, the activity concentration of 226Ra, 232Th and 40K in four types of chemical fertilisers were measured by gamma spectrometry system. The concentration range for 226Ra, 232Th and 40K were obtained from 54±2.2 to 1585±29.4, 6±0.1 to 157±9.1 and 31±1.5 to 1496 ± 32.8 Bq/kg, respectively. The obtained results showed that the average of radiation hazard parameters for the fertilisers were … Show more
