an isotope undergoes radioactive decay by emitting radiation that has a -1 charge. what other characteristic does the radiation have?\no some shielding required\no no mass\no large mass\no high penetrating power

Answer

Brief Explanations:

When an isotope emits radiation with a - 1 charge, it is emitting beta - particles (electrons or positrons in some cases, but here we focus on the common electron - like beta decay). Beta - particles have a very small mass (the mass of an electron). They do require some shielding (less than gamma rays but more than alpha particles). Their penetrating power is moderate, not high like gamma rays. Since they are electrons, they have a very small mass compared to protons and neutrons.

Answer:

no mass
