The process involved the tiresome task of the chemical separation of the element, its purification, and the final concentration on a small surface. 92 Since polonium did not emit beta particles that usually interfered in scintillation counting, its use as a radioactive source was most advantageous.
Chadwick's careful surveillance, 25 and he eventually assigned specific research projects to them after a short introductory course which included training in scintillation counting.
Finally, several of the persons mentioned must act as counters in scintillation observations when the ordinary disintegration apparatus or the mass spectrographs are used. 170
Our particular kind of work requires the close and continued collaboration of at least half a dozen highly specialized workers: one for preparing and calibrating the screens and the absorption foils used in scintillation counts; one for preparing the disintegration apparatus itself, the substances which are to be investigated in it and the gas with which it is filled; one for working the mass spectrograph and its auxiliary instruments; and one specialist on photography ...
It's called a scintillation counter, and it's been specially adapted for this search.
And farther, that that motion, whereby the fire worketh, is dilatation, and contraction of itself alternately, commonly called scintillation or glowing, is manifest also by experience.
The gamma camera has a large crystal detector (called a scintillation crystal).
New apparatus such as scintillation counters and photographic emulsions were developed in order to detect individual particles.
Every kind of scintillation flashed from the gem-incrusted dishes.
The technical term is "scintillation," connoting minimal signification, the minutest re-marking that makes a wink of a photon.
