"More research is necessary before we will be able to determine what the effects are from low-level radiation."

The consequences of low-level radiation are often more psychological than radiological.

Only low-level radiation is left in the reactor, which poses no health risk, spokesmen said.

Given the uncertain effects of low-level radiation, there is a pressing need for good quality research in this area.

The soil around the complex in several locations is contaminated with low-level radiation.

The question is of concern because such low-level radiation is pervasive.

His internal sensors reported low-level radiation, nothing for him to worry about.

In a clean environment, the theory goes, the effects of exposure to low-level radiation will be purged from their systems.

One of Scheer's main research interests was low-level radiation and its effects on human beings.

He added, "If this is true, we could save billions of dollars a year now spent trying to protect people from low-level radiation."
