As thorium-232 undergoes radioactive decay, it emits an alpha particle, with accompanying gamma radiation, and forms radium-228. This process of releasing radiation and forming a new radionuclide ...

Thorium-228 is dried down to thorium nitrate for shipping to a customer. The isotope is a byproduct of actinium-227 production at ORNL that has medical uses as well.

Well-known examples are uranium and thorium, but also included are naturally occurring long-lived radioisotopes, such as potassium-40. Another 50 or so shorter-lived radionuclides, such as radium-226 ...

Detected ionization decreases when smoke particles absorb the ions. Alpha, beta, and gamma emitters down the decay chain (neptunium series). Propane lantern mantle Thorium-232, alpha Alpha, beta ...

It’s the rarest particle decay ever discovered. Scientists have clinched the case for a special type of decay of subatomic particles called kaons. Further study of the rare decay could reveal a ...

Even ignoring the irony that thorium oxide is primarily an alpha (He +) emitter and thus not a ‘negative ion’ source (which would be beta decay, with e –), thorium oxide isn’t something ...

In nature, uranium isotopes are typically found in radioactive equilibrium (i.e. the activity of each of the radioactive progeny is equal to the activity of the uranium parent isotope) with their ...

Chainsaw chains are the part of the chainsaw blade that cuts through wood. Over time, the chain can stretch slightly during use, which reduces the saw’s wood-cutting effectiveness, slows down ...

This food chain shows a leaf is eaten by a worm, which is then eaten by a bird. The arrow means 'is eaten by'. A food chain always starts with a producer. This is an organism that makes its own food.
