And the decay releases more particles with high energy.

Hot particles released into the environment may originate in nuclear reactors.

The crash of the Kosmos 954 satellite released hot particles from its nuclear engine.

Before that, you knew different industries were releasing different particles.

Alas, the opposite is true: nuclear plants release radioactive particles into the environment on a routine basis.

Power plants release mercury, other metals, acid gases, and particles that harm people's health.

As radioactive materials decay, they release particles that can damage the body and lead to cancer, particularly cesium-137 and iodine-131.

The antitail was formed from particles released between February 6 and March 1, 1957.

They really only need to take care of the Plutonium reactor as that could release radioactive particles that will have long life.

The solar wind is a stream of charged particles released from the upper atmosphere of the Sun.
