What kind of high energy radiation is released from nuclear reaction ?

The energy released in a nuclear reaction may appear only in one of these three ways Kinetic energy of the products. The emission of gamma rays. And gamma rays are emitted by unstable nuclei in their own transition that is from a high energy state that than goes to a lower energy state that is properly known as gamma decay.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
