She had also already found some exotic high-energy particles in nearby space, but nothing so unusual as to warrant attention.

It's just picking up very high-energy particles natural to the atmosphere.

But space is full of very high-energy particles: cosmic rays.

Deep inside the cloud of high-energy particles, radio contact was impossible.

The high-energy particles produced by radioactive materials are called radiation.

A lot more energy comes out as high-energy particles.

Semiconductor detectors for high-energy particles are used in large numbers.

"How do you explain the high-energy particles flooding out of that system?"

The first one vanished in a haze of high-energy particles and radiation.

Not only is light blocked, but so are most high-energy particles from space.
