Meaning and Definition
Penetrating rays emitted from radioactive substances, discovered by Henri Becquerel.
A historical term for the radiation (specifically alpha, beta, and gamma rays) emitted spontaneously by uranium and other radioactive elements; now largely superseded by more specific terms.
Dialectal Variation
British vs American Usage
Differences
No significant differences; the term is equally historical and obsolete in both varieties.
Connotations
Purely scientific and historical. Carries connotations of pioneering discovery in physics.

FAQ
Frequently Asked Questions
Yes, the radiation historically called Becquerel rays (ionizing radiation) is harmful to living tissue, as Becquerel and the Curies discovered through personal exposure.
No. Becquerel rays are emitted spontaneously from radioactive elements. X-rays are produced artificially, typically by bombarding a metal target with electrons. Both are forms of ionizing radiation.
Because further research by Rutherford, the Curies, and others differentiated the emissions into distinct types (alpha, beta, gamma rays) with different properties, making the blanket term obsolete.
The becquerel, the SI unit of radioactivity (one disintegration per second), is named in honour of Henri Becquerel, commemorating his discovery of the rays that revealed radioactivity.
Penetrating rays emitted from radioactive substances, discovered by Henri Becquerel.
Becquerel rays is usually technical/historical (scientific) in register.
