People line up for radiation screening at Koryama in Fukushima prefecture in March 2011. Japan's Teijin Chemicals Limited said Wednesday it had created a plastic that emits a blue light when exposed to radioactivity, which it says will lead to cheaper radiation detectors.

Japan's Teijin Chemicals Limited said Wednesday it had created a plastic that emits a blue light when exposed to radioactivity, which it says will lead to cheaper radiation detectors.

It said it will soon produce a commercial version of the polyester resin -- named Scintirex and developed in collaboration with two universities -- enabling researchers and firms to create cheap detectors and medical devices.

Scintirex "will help to reduce the total cost of by slashing the production cost of scintillators to one tenth or less of current levels", the company said in a statement.

A scintillator is the core of a radiation detector.

A 9.0-magnitude quake and tsunami in Japan in March triggered the world's worst since Chernobyl 25 years ago, with radiation leaking into the air, soil and sea from the damaged Fukushima Daiichi .

Thousands of people were evacuated from their homes and exports of certain foods halted amid radiation fears.

They would have had these out sooner, but they couldn't tell if the prototypes were working or not. As soon as they were hooked up, they started going off.

They might have to outsource the manufacuring due to technical difficulties.

So what sort of radiation does this detect? Alpha particles? Beta radiation? Gamma rays?

It's not much use if you detect the 'wrong kind' of radiation.
