Measurement of gross alpha, gross beta and determinationof radium-226 content in various types of water samples/ Mohd Azmi Wahid

The commonly determined physical properties of water are colour, residue (solids), odour, temperature, specific conductance, and turbidity. All of these properties either influence or reflect the chemistry of the water. Solids, for example, arise from chemical substances either suspended or dissolved in the water and are classified physically as total, filterable, no filterable, or volatile. This thesis was study about measurement of gross alpha/beta and determination Radium-226 that content in various types of water samples. There are seven water samples was collected which is drinking water, mineral water, home tap water, lab tap water in UiTM, rain water, lake section 7 and ex-mining lake water Kampung Gajah Perak. In my investigation water sample from ex-mining Lake Kampung Gajah Perak was the highest content Radium-226 and gross alpha/beta activity.
