Levels of ionizing radiations in selected quarries in Nyamira County, Kenya.

It has been shown through a survey by World Health Organization and International Commission on Radiological Protection that certain materials (stones) sourced from quarries and used for the building are radioactive. In Kenya, underground stones which are sourced from embedded rocks are used in construction of most of the permanent buildings, yet Kenya has not adequately radio-profiled sources of building materials to determine whether the construction materials contain radionuclides that emit ionizing radiations yet are used for building. Consequently, Kenyans could be at risk of exposure to high levels of ionizing radiations by living in stone houses that are not radio-profiled.
