Radiation be any of a number of different energy sources: light, heat or nuclear sources.
The mantle is made of rock, which light cannot pass through.
They occur in the upper mantle and the convections come from the inner core but travel to the upper mantle.
Convection currents take place in the mantle.
Earth's rotation causes mantle convention. But you already knew that! :P
radioactive decay takes place, which produces lot of heat and causes the mantle to flow in convection currents veena
Shortwave radiation occurs from the sun which is known as K*. Longwave radiation is known as L* and can occur from clouds etc.
Simply put, the material that makes up Earth's mantle is opaque, so heat cannot pas through it by radiation.
Because the mantle rock is opaque, most radiation (except for radioactivity from decay of uranium and other radioisotopes) cannot pass through it. Radiation from radioisotopes (e.g. x-rays, gamma rays, beta rays) occurs in earth's mantle and can go significant distances before being absorbed by the rock, helping to keep the mantle hot.

No where.
Radiation can occur in a vacumn.

It can occur through conduction, convection and radiation.
