The preparation of three compounds of americium—AmO2, Am2(SO4)3, and anhydrous AmCl3—is described. These compounds have been used in the determination of the alpha half-life of Am241. A value of 7·187 ± 0·007 × 106 α/min/μg was obtained for the specific activity, from which...
The expected working life of an ionization-type smoke detector (described in the opening essay) is about 10 years. In that time, americium-241, which has a half-life of about 432 y, loses less than 4% of its radioactivity. A half-life of 432 y may seem long to us, but it is not...
The measured specific power of 0·1145 W/g has been used to calculate the half-life of americium-241 as 432·7 ± 0·7 yr. This calorimetric values is significantly different from the half-life of 458·0 yr as determined by absolute alpha (specific activity) low geometry counters as ...
