How did nuclear radiation get discovered
from placing uranium salts on a photographic plate and realized the plate had darkened
Who discovered nuclear radiation
Henri Becquerel
radiation
The penetrating rays and particles given off by radioactive source
radioactive decay
an unstable nuclei tries to attain stability by emitting radiation in a process
What does Alpha radiation consists of
Helium nuclei
3 types of radiation
Alpha, beta, and Gamma
What does beta radiation consists of
Electrons
Gamma radiation consists of
high energy electromagnetic radiation
What penetrating power goes the farthest
Gamma radiation/electromagnetic radiation
Positron emission
A proton breaks down into a neutron and a positron
Electron Capture
An atom pulls in an electron to a proton to make a nuetron
Alpha decay
Atomic NO. -2, Mass No. -4
Beta Decay
Atomic No. +1, Mass no. Same
Gamma radiation
Atomic No. +1, Mass No. same
Positron or electron decay
Atomic No. -1, Mass no. same
Nuclear Fission
breaking down into smaller more stable nuclei
