No Photon
This radionuclide found in organisms can be used for dating.
What is Carbon-14?
Twin high-energy gammas are produced by this radionuclide commonly used for gamma irradiation.
What is Cobalt-60?
This naturally occurring fissile nuclide is enriched to <20% in our fuel elements.
What is Uranium-235?
This nuclide makes up the poison sections of our control rods.
What is Boron-10?
This gaseous radionuclide is formed from irradiation of air.
What is Argon-41?
This tiny radionuclide is found in self-luminous exit signs.
What is Tritium (Hydrogen-3)?
The vast array of gamma energies from this nuclide make it valuable for performing Quality Control checks on our gamma specs.
What is Europium-152?
This fissile alpha emitter is commonly found in smoke detectors.
What is Americium-241?
This fission product has the largest known (n,γ) cross section.
What is Xenon-135?
This radionuclide is produced by activation of oil poured down the lazy susan tube and contaminates all our TRIGA tubes.
What is Selenium-75?
This beta emitter is used in our GSM and CAM sources.
What is Technetium-99?
6 MeV gamma rays from this short-lived radionuclide are why we disturb the pool water to prevent it from reaching the surface.
What is Nitrogen-16?
This fissile nuclide created in our core is also found in the Howtizer.
What is Plutonium-239?
This stable fission product acts as a significant neutron poison in our core.
What is Samarium-149?
Rabbit samples contaminated with sweat might exceed activity calculations due to the formation of this nuclide.
What is Sodium-24 OR Chlorine-38?
This beta emitter, along with its beta emitting decay product, is a source of much of the radioactive heat in spent fuel.
What is Strontium-90?
This decay product undergoes isomeric transition producing the characteristic gamma rays in our Shepard source.
What is Barium-137m?
This fissile nuclide is used as a neutron source owing to its 3% Spontaneous Fission branching ratio.
What is Californium-252?
This isotope possesses the largest (n,γ) cross section of any stable nuclide.
What is Gadolinium-157?
This gaseous radioisotope released in the Uranium Series is responsible for a majority of background radiation.
What is Radon-222?
This short-lived alpha emitter has been used as a poison due to its high internal damage and lack of easily detectable gamma radiation.
What is Polonium-210?
The most common terrestrial isotope of Argon differs from those produced in stellar nucleosynthesis due to decay of this lightest primordial radionuclide.
What is Potassium-40?
This unusually long-lived fissile alpha-emitter is the heaviest isotope with a half-life over a million years.
What is Curium-247?
This extremely long-lived radionuclide is commonly used to eliminate thermal flux for experimentation
What is Cadmium-113?
Formation of this nuclide might explain a drop in power when using the rabbit without gloves.
What is Chlorine-36?
