I have taken Radio iodine dose for hyperthyroid of 10Mci on 31.08.18 at that time I was having constipation for 3-4 days, then I took some medicines like AKPils, trifalachurna but it doesn't work (passed little bit). Then one of doctor suggest me lactulose and which cleaned my stool. I have question that, the after RAI does patient emits radiation thru urine, stool & sweat, in my case I had passed urine very often but stool doesn't pass, is radiation affect inside my body? I wants know whether any chance of stomach, colan cancer if yes then what precaution I should take.
