Low pressure multi-wire proportional chamber (LPMWPC) provides excellent position and time signals for the radioactivebeam induced reactions.
低压多丝正比室为放射性束核反应的靶前粒子提供位置和时间信号。

The food is not exposed to radioactive materials — rather, it's zapped with a radiation beam, which the EPA compares to a big flashlight.
食品并不暴露在放射性物质中——相反，它受环保局比喻为大手电光束的辐射光束照射。

Since pure radioactive ion beam can be implanted into material directly, research on solid physics especially on impurity and defect in semiconductor become possible.
