In this lesson, students will simulate the randomness of decay in radioactive atoms and visualize the half-life of a sample radioactive element. This lesson can be completed in two (2) 45-minute class ...
Astatine is one of the least-studied elements of the periodic table, because all isotopes of astatine are unstable, with the longest half-life barely exceeding 8 hours. Thus, only radiochemists at the ...

Half-life: 25 years after the Chernobyl meltdown, a scientific debate rages on
In May 2016, close to the northern border of Switzerland, radiochemist Zeynep Talip suited up for the hot laboratory (Hotlab) at the Paul Scherrer Institute (PSI), where experiments with radioactive ...
Analysis of meteorite Erg Chech 002 shows that the radioactive isotope aluminum-26 was unevenly distributed in the early Solar System, overturning previous theories. (Yuri Amelin) A little over four ...
Gadget Review on MSN: This battery uses radioactive decay to deliver 100 years of power
Nuclear battery from NRD LLC promises 100-year lifespan using Nickel-63 decay, but delivers only nanowatts for sensors, not consumer devices.
CNN: Three months, three missing radioactive items. Here’s what you need to know
What do a capsule in Australia, a cylinder in Thailand and a camera in the US have in common? All three contained radioactive material and went missing over the past three months, in what experts say ...

New Scientist: We need more radioactive drugs. Can we make them from nuclear waste?
The rise of a new generation of radiotherapies means we will soon need much greater quantities of radioactive atoms. That's why companies are scrambling to refine them from all manner of radioactive w ...
