Basics
What type of electromagnetic radiation is gamma radiation?
High-energy electromagnetic radiation
Gamma decay often follows which two types of decay?
Alpha and beta decay
Gamma rays are used in this cancer treatment method.
Radiation Therapy
This device is used to monitor radiation exposure.
Dosimeter
Gamma rays can do this to atoms, potentially causing biological damage.
Ionize atoms
Does gamma radiation have mass or charge?
No mass and no charge
This type of particle is emitted in gamma decay.
A gamma photon
Gamma rays are used for this purpose in food preservation.
Sterilization or pasteurization
These materials are commonly used for gamma radiation shielding.
Lead or concrete
Gamma rays can damage this part of the cell, potentially leading to cancer.
DNA
Compared to alpha and beta particles, how penetrating is gamma radiation?
The most penetrating
A correct balanced gamma decay equation for Cobalt-60.
^{60}{27}\text{Co} \rightarrow ^{60}{28}\text{Ni} + \beta^- + \gamma
Gamma radiation is used in this method to inspect metal welds.
Industrial radiography
Increasing this reduces your radiation exposure significantly.
Distance from the source
Gamma radiation does not typically cause this kind of nuclear reaction.
Nuclear transformation
During gamma decay, the nucleus undergoes this kind of change.
A drop to a lower energy level without changing its atomic number or mass
Gamma decay does not change this property of the nucleus.
Number of photons
This non-invasive surgical tool uses focused gamma rays.
Gamma knife
These tools allow safe handling of radioactive materials.
Robotic arms or long-handled tongs
In this effect, a gamma photon causes an electron to be ejected from an atom.
Photoelectric effect
These materials are effective at blocking gamma rays.
Thick lead or concrete barriers
After emitting gamma radiation, the nucleus returns to this kind of energy level.
A lower energy state
Gamma radiation helps track chemical or biological processes through this technique.
Radiotracers
The three main principles of radiation protection.
Time, distance, and shielding
This occurs when a gamma photon bounces off an electron and loses energy.
Compton scattering
