<u>Answer:</u> The radiation emitted will have negligible mass number.
<u>Explanation:</u>
Radioactive decay is defined as the process in which an unstable nuclei breaks down into stable nuclei via various methods.
An isotope undergoes a radioactive decay to attain stability.
There are three types of decay process, but the process in which the emitted radiation carries a charge of -1 is beta decay.
Beta decay is defined as the decay process in which a neutron gets converted to a proton and an electron. In this decay process, beta particle is emitted. The emitted particle carries a charge of -1 units and has a mass of 0 units. The released beta particle is also known as electron.

Hence, the radiation emitted will have negligible mass number.
