When does the speed of radiation decrease? What has to happen in order for it to decrease?

EM radiation doesn't change speed. Light always travels at 3.0x10^8. This is why the equation c=(lambda)v is viable.

Radiation is a form of light, just not visible light. The speed will not change in a vacuum, but it will change as it passes through a different medium, such as glass.
