Radioactivity in cathode ray tubes
Health Physics, 2004While surveying used computer equipment out of a zone posted as a Contamination Area, 100% of the computer monitors surveyed had levels of radioactivity that were significantly above background. The radioactivity was primarily on the front face of the cathode ray tube and was not amenable to decontamination.

Cathode Rays and Some Analogous Rays
Archives of The Roentgen Ray, 1897Abstract The size of the cathodic shadow of an object depends upon its own electric state, as already found by Crookes. If it is negatively electrified the shadow expands. If it is positively electrified the shadow contracts.

The cathode ray oscillograph, since its invention by Braun, has developed along three lines. The major types of tubes are the high voltage tubes with a fluorescent screen, the high voltage tubes with internal photographic equipment, and the low voltage tubes. This paper follows the structural development of commercial tubes.

The paper draws attention to three commercial forms of cathode-ray oscillograph which may be employed in the study of very high-frequency alternating or impulsive electrical phenomena.The behaviour of a stream of cathode rays in electrostatic and magnetic fields is first dealt with, and the penetrating power of cathode rays through matter is considered

Resources, Conservation and Recycling, 1999 Lead and polybrominated flame retardants are the two hazardous materials that can be found in electronic appliances. Particularly, cathode ray tubes (CRT) contain leaded glasses. In a computer monitor, over 98% of the lead is in the CRT. This material is

Cathode-Ray Presentation of Chromatograms
Nature, 1960FROM the results of investigations on nylon capillary columns1, it became apparent that there were two possible applications for the capillary system. The columns could be used to produce very high efficiencies with elution times of 10–60 min., or the high efficiencies could be sacrificed and chromatograms developed in a matter of seconds, with ...

The modern cathode-ray oscilloscope is designed as a measuring instrument, and is the most useful of all electronic test devices. So great is its versatility that workers in every branch of scientific activity now find the instrument to be almost indispensable.

The study of the passage of electricity through gases had lagged behind the corresponding study on metals and liquids. Faraday himself had engaged in research on electrical discharges in gases as early as 1838 but was hampered by the inefficiency of his vacuum pumps.
