How much actinium is in your body? Find out here.
You can use this form to calculate how much actinium your body contains. Enter your weight in either kilograms or pounds and click the "Calculate" button. You must enter a number, not text! Elements for which there are no data will always give a value of zero for the weight, no matter what you put in the weight box.
Hazards and Risks
Hazards and risks associated with actinium: actinium does not occur to any significant extent in the biosphere and so normally never presents a risk. Actinium is studied in a few nuclear research laboratories where its high radioactivity requires special handling techniques and precautions.
