One of the coolest (OK, maybe the coolest) is using radioactive carbon to determine the age of old bones or plants. To understand this, you must first understand radioactivity and decay.

That process is called radioactive decay. And scientists know exactly how long it will take for half of any amount of carbon-14 to decay away. Scientists call that time its "half-life." ...

Save guides, add subjects and pick up where you left off with your BBC account. An alpha particle consists of two protons and two neutrons and is often described as a helium nucleus. It is not the ...

However, you would need an immense amount of new organic matter decay to explain the increase in carbon dioxide in the atmosphere. Where are we hiding all this decay? Nowhere, so that can be ...

He also explains the concept of half-life and carbon dating ... Pupils could explore decay chains and complete equations to show radioactive decay processes. They could also plot graphs of ...

In an article recently published in Biochar, researchers critically assessed the widely used two-pool exponential decay model ...

By reducing such litter decay to a simple mathematical equation, researchers can better understand how carbon and nitrogen cycle through terrestrial systems—and thus improve climate change models.

Figure 1: Regression between the log-transformed water retention time (WRT) and decay rates of organic carbon (OC). Figure 2: Comparison of the relationship for inland waters and marine sediments.

According to the University of Bristol, the battery uses carbon-14 encased in a manufactured diamond to generate power. The radioactive decay of carbon-14, more popularly known for its use in ...

Figure 1: Carbon nanotube immersed in an ultracold quantum ... The nanotube significantly increased the decay rate compared with the plain surface. The problem of time-dependent atom loss at ...
