Simulate Radioactive Decay. Materials for each group: shoe box with lid 80 pennies, 80 dice, or 80 sugar cubes 80 paper clips ... Have students create a chart similar to the one below.

Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a new and faster method for ...

On the periodic table, most elements have at least one stable form. But others have only unstable forms, all of which decay by emitting radiation and transforming into different elements until ...

Radioactive decay is the strange and almost mystical ability for one element to naturally and spontaneously transmute into another. In the process, those elements tend to emit deadly forms of ...

Scientists have developed a supercooled sensor that delivers full radioactivity profiles without chemical tracers.

As it turns out, they probably aren't. After poring over the data, engineers and physicists noted a recurring pattern 33 days long that affected the decay rates of the various radioactive substances.

Fukushima Radioactive Water Leak Chart ... • Some radioactive isotopes rapidly decay. For example, the half life of Iodine-131 (I-131) is about eight days. This means that the activity level of ...

This means that as more of these atoms decay you have a lower rate of radioactive decay. I know can be hard to wrap your head around, so let's model it with a six-sided die. Start with 100 objects.

Some isotopes are stable, while others are radioactive and decay over time, emitting radiation. Carbon-14 is a radioactive isotope of carbon, meaning that it undergoes beta decay, releasing electrons.
