Alpha rays can be stopped by a sheet of paper.

She did her thesis on the alpha rays of polonium.

She could shoot alpha rays from her eyes.

Alpha rays can be very damaging to cells they reach because they unload all their energy in a small area.

Alpha rays were defined by Rutherford as those having the lowest penetration of ordinary objects.

One type had short pentration (it was stopped by paper) and a positive charge, which Rutherford named alpha rays.

The research found that alpha rays may cause damage to cells which only becomes apparent much later when abnormal chromosomes appear.

There were even wild theories that spaceborne alpha rays could cause arcade machines to decay.

Gamma rays usually accompany beta, and some alpha rays.

"Plutonium does not emit deep alpha rays."

He discovered alpha rays.

Microscopically the air molecules smash into the subsonic crowd of molecules like alpha rays.

Ernest Rutherford classifies two types of radiation, alpha rays and beta rays.

"Mainly alpha rays," Chellish murmured almost absentmindedly.

Beta rays are more penetrating than alpha rays, but internal exposure will tend to do less damage because the linear energy transfer is lower.

Mr. Reinig said plutonium emits radioactive alpha rays, small amounts of which can be "completely shielded by a thin piece of paper."

And there are the weirdos, who complain of being bombarded by alpha rays or tailed by the C.I.A.

Alpha rays could be stopped by thin sheets of paper or aluminium, whereas beta rays could penetrate several millimetres of aluminium.

Radio waves and visible light were clearly waves, while cathode rays, alpha rays, and beta rays were streams of speeding particles.

Studies of Hiroshima and Nagasaki survivors are less informative (the exposure to radon is chronic, localized, and the ionizing radiations are alpha rays).

Note that, astronomical literature tends to write "gamma-ray" with a hyphen, by analogy to X-rays, rather than in a way analogous to alpha rays and beta rays.

Alpha rays (alpha particles) and beta rays (beta particles) were differentiated by Ernest Rutherford through simple experimentation in 1899.

A sample of beryllium was bombarded with alpha rays from the decay of radium in a 1932 experiment by James Chadwick that uncovered the existence of the neutron.

Her doctoral thesis was concerned with the alpha rays of polonium, the element discovered by her parents (along with radium) and named after Marie's country of birth, Poland.

During his investigations of radioactivity, Ernest Rutherford coined the terms alpha rays, beta rays and gamma rays for the three types of emissions that occur during radioactive decay.
