Radioactivity and Nuclear Energy Guided Notes
Introduction to Radiation Video 11/30
_________________: the emission of energy as electromagnetic waves or as moving
________________ particles, especially _______-____________ particles which cause
ionization.
Two types:
1. Electromagnetic Radiation (we will get to this in Physics )
2. _____________________
Nuclear Radiation: THREE TYPES

Alpha radiation: An ________________
nucleus emits a Helium atom made of two
_______________ and two
______________. When this Helium atom
collides with other particles what occurs?
What happened to the mass number of the
parent nucleus?
Alpha particles are _____________, highly ionizing but not very _________________.
They won’t even travel through a sheet of paper!
Ionization: High energy alpha particle radiation hits another atom ______________ an
____________. Electrons are ____________, so if you lose a negative electron the
charge becomes more _________________. What happens if the alpha particle causes
an atom to lose a proton?
What is happening in the diagram shown? Why is it important to have a continuous
current of positive and negative charges? What real world example is this diagram
illustrating?

Beta Radiation: A neutron in the nucleus turns
into a _____________ plus an _____________.
The proton stays in the _____________ and
the electron leaves the atom with
_______________________, and we call it a
beta particle. CHECK: Which part is the beta
particle?
Beta particles are moderately ___________,
moderately ________________ and
moderately _________________. Beta
Radiation can be used to create Aluminum Foil. What is the importance of too little or
too much radiation when making the foil?

Gamma Radiation: A _________ frequency
_________________ wave. There is NO change in
protons or neutrons therefore the mass stays the
__________. Even though the numbers DO NOT
change there is still enough energy for
_____________ to occur. Gamma is the
__________ penetrating and the _____________
ionizing of the three types of radiation. We can use
gamma radiation for _________________.
