Part A: Introduction (00:18)

FREE PREVIEW

This video covers beta-plus decay, or positron emission. It shows how to write nuclear equations and gives examples of beta-plus decay's uses.

Part B: Positrons (09:30)

In beta-plus decay, or positron emission, a proton converts into a neutron and an electron that has a positive charge. The positively charged electron, a positron or beta-plus particle, is a form of anti-matter. Beta-plus decay rarely occurs naturally.

Part C: Positron Emission Tomography (06:42)

Experts use medical images taken with positron emission tomography to detect tumors. PET scans can detect high concentrations of glucose that occur when cancer cells reproduce.

Description

In Shedding Light on Nuclear Radiation Episode 4: Beta-Plus Decay, we introduce students to beta-plus particles, also known as positrons. Beta-plus particles are a form of anti-matter. Though beta-plus particles don’t really exist in huge quantities naturally on Earth, scientists have learned how to actually make atoms that emit them! Beta-plus particles have now become a major tool for doctors to diagnose a wide variety of cancers.
