The alpha particles emitted by ac-225 are relatively feeble, so they don't do much damage past the targeted area. Even a little healthy skin stops them dead. And its half-life is 10 days, meaning half of it's gone after 10 days, so it doesn't hang out in the body for long.

"I think we're very hopeful that this will have tremendous impact for some cancers right now that really don't have highly effective treatments," Birnbaum said.

Early clinical trials have found that ac- 225 has the potential to treat leukemia, melanoma and other cancers, like those of the breast and the prostate.

If Actinium targets cancers and kills it without destroying healthy tissue, this will be more widely use than chemo therapy a multi billion dollar drug. We could be looking at the holy grail of tratments for a wide range of cancers.
