Colony irradiation is unlocked after destroying Earth.
It is only possible to irradiate colonies that you have purchased at least once before. If every colony has been purchased at least once, then each colony has the same probability of being irradiated.
Only one irradiation type can be researched at a time.
Each successful irradiation doubles the production of a random colony.
The effect of colony irradiation is exponential, which means that it can grow very quickly.
For example, a colony with a Level 2 irradiation will have a BPS multiplier of 4, but a Level 5 irradiation will have a multiplier of 32.
If the irradiation process is unsuccessful, the player will get some free bacteria instead.
The amount earned is determined by the formula:
BPS × RandomMultiplier × ResearchDurationInSeconds
RandomMultiplier - a random number between 0.05 and 0.2
