    DAMN IT - why don’t we all read why it’s so clear that Minister Yeo, MESTECC and all the protesters are telling outright LIES about all the LAMP residues and their environmental ‘risks’!

    Abstract

    The objectives of this study were to determine the natural radioactivity concentrations (226Ra, 228Ra and 40K) in soil, water and plant due to the application of Condisoil®, soil-to-plant transfer factor and radiological hazard index due to the application of Condisoil®.


    A total of 4 soils, 14 waters and 4 plants samples have been analysed using gamma spectrometry system. The results showed that the activity concentrations of 226Ra, 228Ra and 40K in soils treated with Condisoil® ranged from 13.8 - 17.6, 15.7 - 21.0 and 44.5 - 57.7 Bq kg-1, respectively. The activity concentrations of 226Ra, 228Ra and 40K in plants ranged from 5.0 - 18.5, 0.1 - 1.5 and 42.7 - 321.8 Bq kg-1, respectively.


    In addition to that, the activity concentrations of 226Ra, 228Ra and 40K in water was in the ranged of 0.3 - 0.9, 0.3 - 3.9 and 1.4 - 11.6 Bq L-1, respectively. The soil-to-plant transfer factor for 226Ra, 228Ra and 40K were in the ranged of 0.42 - 0.71, 0.01 - 0.08 and 0.85 - 5.34, respectively.


    The radiological hazard assessment found that the radium equivalent index was lower than the recommended limit of 370 Bq kg-1.

    (= 0.37 Bq/gram). Therefore, this study concludes that the application of Condisoil® as soil amelioration does not contribute to the accumulation of natural radionuclide in the environment, as well as does not pose a significant radiological risk to humans.
