Swabbing - Horse Racing (gambling) and Cherenkov radiation (sh)


Swabbing - Horse Racing (gambling)


The taking of blood and/or urine samples from a horse for analysis by a testing laboratory. The stewards may direct any horse to be swabbed before or after it has raced, irrespective of where it finishes in the race. The samples are tested by the laboratory for any irregularities or prohibited substances or drugs. A positive swab is one which has been found to contain a prohibited substance.

Cherenkov radiation (sh)




Light produced by charged particles when they pass through an optically transparent medium at speeds greater than the speed of light in that medium.

For example, when electrons from a nuclear reactor Travel through shielding water, they do so at a speed greater than that of light through water and they displace some electrons from the atoms in their path. This causes emission of electromagnetic radiation that appears as a weak bluish-white glow. The phenomenon is named for Pavel A. Cherenkov (1904-1990), who discovered it; he shared a 1958 Nobel Prize with Igor Y. Tamm (1895-1971) and Ilya M. Frank (1908-1990), who interpreted the effect.
