Radiation Safety Quiz

What is radiation?
The emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles that cause ionization.
Suff that makes you glow in the dark
A really cool country music band
Causes zombies
Radioisotopes are stable isotopes of an element that decays or disintegrates spontaneously
True
False
What is an alpha particle
The most dominant particle in a nucleus
The opposite of a beta particle
A helium nucleus without electrons
Particle from the nucleus that will penetrate your skin
What are two types of Beta decay
Alpha and beta decay
Beta one and Beta 2
Positron and Fast Energetic Electron
Cool music from Mozart
Gamma Nuclear Radiation is
occurs when a unstable nucleus changes from a higher energy state to a lower energy state through the emission of electromagnetic radiation .
Emission of photons
Requires lead shielding
Does not directly lead to a different radioisotope
All of the above
Neutron activation is
What results from gamma decay
What causes elements to initially decay
The process in which neutron radiation induces radioactivity in materials, and occurs when atomic nuclei capture free neutrons, becoming heavier and entering excited states.

Sun burns are caused by ionizing radiation emitted from the sun on a hot day
False
True
Depends
What would be considered radioactive decay
The spontaneous breakdown of an atomic nucleus resulting in the release of energy and matter from the nucleus.
Unstable nuclei that does not have enough strong force binding energy to hold the nucleus together.
