Radiation and You!

[chunks]

I'm not very articulate, so here's my idea in clump form:
At a certain point in their evolution, bugs become radioactive. Hives spread radiation. Radiation [?corrupts] the ground, forming minable *radioactive material*.
You can not build on [?or near] radioactive ground, except perhaps for a specific type of mining drill, and [?upgraded] belts/arms. Radiation could cause electrical interference, making drones unable to fly through it [?without proper upgrades]. This could easily and intuitively solve the late game "tower creep" problem.
Being in a radioactive field harms the player, slowly draining your life while exposed. Prolonged exposure could cause radiation sickness, which could have a number of effects (blurred vision, slowed movement, damages/repulses/disables drones, etc). Radiation suit armor, or some kind of power armor module could be used to combat these problems.
All of this provides a source of material for nuclear power plants, makes endgame bugs/hives more difficult to deal with, introduces a new resource at a certain point in the game, and has a myriad of other potential uses.
Thoughts?
