This reproduction of a 24" x 84" radiograph shows the internal detail of an Egyptian mummy in its sarcophagus. This film record, made a decade ago, remains available for examinationi anid study.
"penetrates" for the scientist ..
When objects or specimens must not be "6opened" for investiga- tion, x-rays reveal hidden details.
tRACERS -radioactive isotopes that I emit radiation for autoradiography- give biologists, pathologists, and botan- ists a potent weapon in learning life proc- ess secrets. Successive microradiographs of radioactivated plant and animal speci- mens tell the metabolic story. In applied research, fungus and insect damage to timber is uncovered by radiography to lead to be-tier preservative technic.
Radiography "penetrates" for the sci- entist when he must get facts from inside his subject without destruction. The data he records on x-ray film and high resolu- tion plates are lasting . . . available for careful study and examination at any time.

Developed by RCA as an aid to blind bombing in wartime, Shoran is anew radar yardstick for world mapping
SHORAN- a surveying sysfem with pin-polf ucnury
One small error in a map can be costly in the location of an oil well or mining property. But with Shoran, vast areas can now be charted by plane with an error of less than twelve inches in five miles-and in a miatter of minutes or hours as opposed to weeks or months that would be re- quired by laborious surveys made on the ground. Shoran is called one of the most important geographic in- ventions since the compass.
Shoran can also direct a plane flying in a blackout or heavy overcast with such accuracy that during the war it was Dossible to drop bombs only a
few hundred feet ahead of completely invisible advancing troops below with unerring precision.
Just as Shoran is a revolutionary stride forward in map-making, so do all RCA products represent the far- thest point of progress in their fields.
And when you buy anything made by RCA or RCA Victor, you are sure of getting one of the finest instru- ments of its kind science has achieved.

NBC Network.
UIitil recenitly a closely guarded military secret, Shoran was de- veloped at RCA Laboratories- a world center of radio and elec- tronic research. The same skills that developed Shoran keep RCA and RCA Victor outstanding in radio, broadcasting, tele visioni anid recorded enitertainmenit.
