Ionization by Particles (3) Flashcards
1
Q
Specific Ionization
A
The number of Ion Pairs per unit length of a particles path
2
Q
Total Ionization
A
The total number of Ion Pairs produced along the particle path.
3
Q
Ionization of Alpha Particles
A
Because of how slow they travel (5% speed of light) and their mass of 4 (heavy), they have a high Specific Ionization
4
Q
Ionization of Beta Particles
A
Because of how fast they travel (99.95% speed of light) and mass (1/1840 unit mass) their Specific Ionization is much smaller than that of an Alpha Particle
