Americium has been found in New England
Detection of radioactive materials in the soil in Fukushima Daiichi Nuclear Power Station, TEPCO Press Release, April 27, 2011:
As part of monitoring activity of the surrounding environment, we conducted an analysis of plutonium contained in the soil collected on March 21st and 22nd at the 5 spots in Fukushima Daiichi Nuclear Power Station. [...]
Besides, as the result of the americium and curium analysis in the soil from 2 samples among the 3 periodic sampling spots in which plutonium was detected on March 28th amerium 241, curium 242, 243, and 244 were detected.
We have reported the results of analyses to the Nuclear and Industrial Safety Agency and the government of Fukushima Prefecture.
We will continue to conduct the similar analysis.

Best guess for Americium Half-life is 432.2 years

Thanks.

The longest-lived and most common isotopes of americium, 241Am and 243Am, have half-lives of 432.2 and 7,370 years.
rule of thumb is ten elapsed half lives for safe levels…
=4,322 years and 73,700years respectively.

This chart may come in handy too:)

Just change Half-life at the end there to what ever isotope you want to find, gives full run downs.
