When the decay takes place in a sealed container helium gas is collected. name one type of radiation produced in the decay?

One type of radiation produced during decay that results in the formation of helium gas is alpha radiation. Alpha particles consist of two protons and two neutrons, which are emitted from the nucleus during certain types of radioactive decay, such as alpha decay. When an unstable nucleus undergoes alpha decay, it transforms into a lighter nucleus and releases an alpha particle, which is essentially a helium-4 nucleus.
