In the Philippines, legacy mines and active mine wastes pose potential threats since these may contain elevated concentrations of potentially toxic elements (PTEs) high natural radioactivity. this study, from Philippine Iron Mine (PIM), Barlo (BM), Rapu-Rapu (RRM) tailing Padcal (PM) were analyzed to determine fifteen (15) PTEs activity radionuclides. Several quantitative risk indicators radiol...

background: vegetation (food stuff) is grown in soil that contains many radioactive elements such as 238u (uranium), 232th (thorium) and 40k (potassium), which may get deposited either due to radioactive fallout or/and by absorption from the soil and can pose serious health hazards. materials and methods: natural radioactivity, radiological hazards and annual effective dose assessment was carri...

The mean annual effective dose from natural radionuclides for users of drilled wells was estimated to be 0.41 mSv, for users of wells dug in the ground 0.05 mSv and for people using water from waterworks 0.02 mSv. The highest effective dose from drinking water was caused by 222Rn (Fig. 2) constituting 75% and 60% of the total effective dose caused by all natural radionuclides for drilled-well u...
