However, the element of a risk is the cloud cover under which negotiations take place. Too frequently, this is the scenario that an IH screws up by overanalying the question or the situation.

VDTs can produce low levels of radiation, that's why a CRT contains several pounds of lead to protect the user. The CRT however is not the only concern, a malfunction of the elctronics can casue the radiation level to exceed safe levels. The VDT should have safety circuits installed to prevent this and the FDA highly regulates the manufacture of these products. So the answer is that in theory yes there could be a cancer risk, but the reality is that there probably is not.
