Would Creating a Radiation-Free Environment Make Time-Travel in The Past Possible?

So, one of the main reasons that physicists believe with time travel into the past impossible is because it would create a 'paradox'. Hawking states that if a direct rift in time were created, radiation from the sun, everyday objects, ect. would pass between the two time-zones and create a loop of exponentially increasing energy... therefore the rift in time or "worm-hole" would self-destruct.

I was thinking that if an environment (or room) were created that somehow sterilized radiation or was free from it, physicists could travel back in time into that room and avoid the effects of radiation feedback. In a room without radiation, a there would be no feedback between the two time-zones and travel into the past would be possible!

Anybody else think this idea is worth further thought? Are there any faults in my thinking others can see?

So, in a "radiation free" environment where would the energy come from to power whatever mechanism was used to TT, where would the energy come from to "power" the living creatures who were the occupants of the mechanism (it's a bit difficult for humans to exist if their body temperature falls much above or below 98.6 degrees F) and where would the energy come from for them to even see where the gadget was so they could climb aboard it? All matter has energetic fields associated with it - gravity, EM, strong and weak fields.

The problem with a radiation free zone is that the temperature of the zone would be absolute zero. Electrons don't orbit, photons are not emitted and none of the rest of nuclear physics does its "thing". (Not to mention that quantum uncertainty posits that you can't have a system with all fields set to zero because you would simultaneously know the exact position and velocity of particles - if you had instruments that required no energy to make the measurements. )
