Item Geological interactions and radio‑chemical risks of primordial radionuclides 40K, 226Ra, and 232Th in soil and groundwater from potential radioactive waste disposal site in Ghana(Springer, 2021) Akortia, E.; Glover, E.T.; Nyarku, M.; Dawood, A.M.A.; Essel, P.; Sarfo, E.O.; Ameho, E.M.; Aberikae, E.A.; Gbeddy, G.This study assessed the infuence of geological depth and formation on activity concentrations of 232Th, 226Ra and 40K in soil and groundwater, and radio-chemical health risks. Preference ranking organisation method for enrichment evaluation and geometrical analysis for interactive aid indicated signifcant correlation between 232Th and 40K, thus indicating potential similar primordial origin. Deepest depth rocks at 145 m and 148 m constituted of dark coloured silicifed schist exhibited minimal activity with potential hydro-geological interactions with groundwater. Age-dependent annual efective ingestion dose for 226Ra and 232Th are higher than the UNSCEAR reference dose, thus the groundwater is unsuitable for long-term consumption.Item Radiation exposure control from the application of nuclear gauges in the mining industry in Ghana(Health Physics, 2010-05) Faanu, A.; Darko, E.O.; Awudu, A.R.; Schandorf, C.; Emi-Reynolds, G.; Yeboah, J.; Glover, E.T.; Kattah, V.K.The use of nuclear gauges for process control and elemental analysis in the mining industry in Ghana, West Africa, is wide spread and on the increase in recent times. The Ghana Radiation Protection Board regulates nuclear gauges through a system of notification and authorization by registration or licensing, inspection, and enforcement. Safety assessments for authorization and enforcement have been established to ensure the safety and security of radiation sources as well as protection of workers and the general public. Appropriate training of mine staff is part of the efforts to develop the necessary awareness about the safety and security of radiation sources. The knowledge and skills acquired will ensure the required protection and safety at the workplaces. Doses received by workers monitored over a period between 1998 and 2007 are well below the annual dose limit of 20 mSv recommended by the International Commission on Radiological Protection. © 2010 Health Physics Society.
