You can use this form to calculate how much francium 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 francium:

Francium does not occur to any significant extent in the biosphere and so normally never presents a risk. Francium is studied in a few nuclear research laboratories where its high radioactivity requires special handling techniques and precautions. One could speculate that its chemical hazards would be very similar to those of caesium.
