How much dubnium is in your body? Find out here.

You can use this form to calculate how much dubnium 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 dubnium: since dubnium does not occur at all in the biosphere it never presents a risk, but it would constitute a radiation hazard if enough was ever assembled in one place.
