Radiation due to naturally-occurring substances in the environment.
A type of ionising radiation consisting of He nuclei: 2 protons and 2 neutrons
Type of ionising radiation consisting of fast-moving electrons or positrons emitted from the nuclei of radioactive isotopes
Type of ionising radiation consisting of high-energy photons with a wavelength of 10^-11m or less
Device that can measure the activity of a source via a count rate (abbreviated version).
The process by which ionising radiation ionises gas molecules, creating positive ions that create further ions as they accelerate, leading to electrical conduction as many ions are produced in a short time.
Time for a GM tube to regain its non-conducting state so it can register another count
The time taken for the mass or activity of a radioactive isotope to decrease to half its initial mass or activity.
The number of nuclei in a sample of a radioactive isotope that decay per second.
The probability of an individual nucleus decaying per unit time.
An excited state of the nuclei of a radioactive isotope that can be quite long-lived
The work done to separate a nucleus into its constituent protons and neutrons.
Binding energy per nucleon
The average work done per nucleon to remove all the nucleons from a nucleus.
The difference in mass between the nucleus and separated nucleons.
Thermal nuclear reactor
Nuclear reactor which has a moderator in the core
The splitting of a large, unstable nucleus into two approximately equal daughter nuclei that are more stable
Rods made of cadmium or boron used to control the rate of nuclear fission by absorbing excess neutrons.
Neutrons released by a fission event
A substance in a thermal nuclear reactor that slows fission neutrons to thermal speeds
A fluid used in a thermal nuclear reactor to prevent it from becoming too hot
A device used to transfer heat energy between the coolant and water to produce steam to generate electricity
A series of reactions in which one reaction causes a further reaction
A substance able to undergo nuclear fission
Minimum mass of the fissile isotope necessary to produce a chain reaction
When radioactive waste is mixed with molten glass and set as a solid glass block
The joining of two smaller, lighter nuclei into a larger, more stable nucleus
Isotope of hydrogen with a neutron
Radioactive isotope of hydrogen with two neutrons
Superheated gas where atoms have been stripped of their electrons
