If a nuclear facility is handling 180 grams of polonium-210, then how many grams of polonium-210 will be left in 230 days? Round your answer 4 decimal places and remember to use labels.

Polonium 210 half life

The Polonium 210 deposited in the average "pack a day" smoker, which has a half life of 158+ days (that means half of it's mass is converted into lead, and the radioactive emissions are delivered directly to your lungs), delivers enough radiation as it decays; to be equal to the amount of radiation you'd get if you had between 300 and 8000 Chest X-Rays per year. Polonium-210 is a decay product radon-222, a naturally occurring radioactive gas (half-life = 3.8 days). Polonium-210 will be released to air through decay process of radon-222, and will be deposited to the earth's surface by rain or snow. Suppose a laboratory has a 31 g sample of polonium-210. The half-life of polonium-210 is about 138 days.

The longer-lived 209 Po (half-life 125.2 ± 3.3 years, longest-lived of all polonium isotopes) and 208 Po (half-life 2.9 years) can be made through the alpha, proton, or deuteron bombardment of lead or bismuth in a cyclotron. History How long does Po-210 stay in the body? The effective half-life of Po-210 -- the time required for the combined action of the physical and biological half-lives to reduce the activity by 50 percent -- is approximately 40 days.
