Understanding the Atom: Radiation Detection by Scintillation, 30 minutes, black and white, sound, 1962. Produced by the Educational Broadcasting Corporation under the direction of the AEC’s Division of Isotopes Development. This semitechnical film describes the scintillation process. Solid and liquid scintillators are shown, a description of a photomultiplier is given, and the pulse-height analyzer principle is illustrated.

Human Radioactivity Measurements, 9 minutes, color and sound, 1958. Produced by AEC’s Los Alamos Scientific Laboratory. This film shows a method developed at LASL to monitor possible intake of radiation by personnel. The liquid scintillation counter is large enough to contain a man and sensitive enough to detect even the minute amounts of his natural gamma radioactivity.

Ionizing Radiation in Humans, 15 minutes, color and sound, 1958. Produced by AEC’s Argonne National Laboratory. Describes the design and operation of ANL’s whole body counter for determining identification, quantity, and location of internally deposited radioelements. Various techniques in accumulation of data are shown.

Liquid Scintillation Counting, 14 minutes, color and sound, 1958. Produced by the Jam Handy Organization for the U. S. Atomic Energy Commission. Describes the use of a liquid scintillator for counting low-energy beta emitters commonly used in biological and medical tracer experiments. Also describes counting techniques, how the counters work, and how a sample is prepared.

FOOTNOTES

This is mathematical shorthand for 1.08 followed by 24 zeros, or 1.08 million billion billion.

Medicines such as “Radithor” and “Radium Water” were manufactured and sold before it was known that overexposure to radioactivity was harmful.
