A radioactive dial marker for the Decca navigational aid / by G. E. Alexander & G. G. Eichholz. : M38-1/15-1958E-PDF
"A small auxiliary unit has been designed for use in conjunction with a Decca Navigational System on survey flights. The unit is intended to trigger a relay system which actuates an aerial camera every time the dial pointer on the Decca dial passes through zero. For this purpose, the pointer tip has been coated with radioactive caesium-137 whose activity is detected by a Geiger tube located above the dial face"--Abstract, p. i.
