But those tests cannot start until a special licence is granted because the process uses radiation and the technology has never been used in a UK prison.

Simulating a dose of radiation is a complicated process.

According to the physicists, when a large black hole captures a smaller object like a medium-sized star the process causes gravitational radiation to be emitted in a preferential direction.

Day takes the idea of returning to past experiments and exposes them to gamma radiation, speeding up the evolution process across 14 tracks.

While ice reflects around 80 percent of the sun's heat, having a cooling effect, blue sea water can absorb up to 95 percent of solar radiation, warming up the sea and accelerating the melting process further.

Radiation is a threat to human health at every stage of the process, from uranium mining to plant operation (even in those new ultra-safe plants) to waste disposal.
