Indoor radon concentrations for buildings of different ages in Universiti Teknologi Malaysia

Radon is a naturally-occurring radioactive noble gas with no colour, odour and taste to which humans are usually exposed. Prolonged inhalation of radon gas is the second main contributor to lung cancer among smokers and non-smokers. This study aimed to compare radon levels between the old (Faculty o...
