Item Embargo Radiological hazard associated with amang processing industry in Peninsular Malaysia and its environmental impacts(Elsevier, 2021) M. S. M. Sanusi; A. T. Ramli; S. Hashim; M.H. LeeContinuous depletion in tin productions has led to a newly emerging industry that is a tin by-product (amang) processing industry to harness mega tons of tin by-products produced in the past. Amang composed of profitable multi-heavy minerals and rare-earth elements. With poorly established safety and health practices in operating plant, amang poses extremely high radioactivity problem associated with high occupational ionizing radiation exposures to workers and continuously impacting the local environment with radioactive contamination from industrial effluent and solid waste into lithosphere and water bodies.Item Embargo The geogenic influence on 220Rn activity concentration in soil gas of Johor state, Malaysia(Springer, 2021) R. Haruna; M. A. Saleh; S. Hashim; K. Hamzah; J. Zainal; N. Rusli; M. S. M. SanusiThe contribution of thoron (220Rn) to natural radiation exposure is commonly neglected. However, dry porous surfaces with relatively high 232Th content can pose a thoron radiation hazard to the environment. Therefore, this research aims at establishing a baseline data for 220Rn activity concentration in soil gas and categorise the measured data based on the geology of Johor state, Malaysia.
