Writing Decay Equations. 19.1. Radioactivity. Particles produced determine type of decay. Radioactive decay is the loss of energy to achieve stability Spontaneous process Where unstable isotopes of one element transform into stable isotopes of another element. A Review From Friday.

Writing Decay Equations
Particles produced determine type of decay
How do we know what the charge is of each type of radiation?
U-238 in which a gamma ray is produced
We will be looking at amount of radiation in this class lab.
How do we detect radiation?
High-energy particles from radioactive decay produce ions when they travel through matter
The probe of the Geiger counter contains argon gas that have no charge but can be ionized by the rapidly moving particle
Momentarily allows a “pulse” of current to flow
Counts the pulse events and records

Penetrating power of radioactive emissions.
Penetrating power is inversely related to the mass and charge of the emission.
AKA: Bigger the particle, the easier it is blocked
