BACKGROUND OF THE STUDY
Water is very ample and
covers about two-thirds of the planet. However, most of it is saline water and
only 2.5% is fresh water. In this small percentage, two thirds of it is locked
in polar ice caps, 20% can be found in remote areas and only 0.08% is
accessible for daily use .
Potable water is essential
for the survival of human life. Without water, our existence is threatened.
However, potable water coming directly from ground water should undergo
different purifying techniques to ensure contaminant free water. The Philippine
Government targets in 2010 to provide 92 to 96 percent of the people of safe
drinking water .
One of the possible
contaminants present in water is radioactive substances. Radioactive substances
such as radium, uranium and thorium occur naturally in the environment .
This study aims to determine the radiological quality of potable water using
liquid scintillation counting. This assesses the gross alpha and beta
particles, known to be internal hazards, present in water.
