Actually, it turns out that heavy water was being used as a coolant. Since I was far away from the core, the radiation was attenuated by the heavy water. Also, the reactor was designed with a automatic SCRAM procedure, so it shut down before it could even get hot enough to melt the fuel rods. (Meltdowns =/= Explosion)
The next user is a normal human who is trapped in the radioactive debris inside of Chernobyl's reactor 4, with no protection against the radiation.
