radiation decay calculator / Regle Radiac / Radiac Regel

I don't suppose anyone has a copy of the instruction manual for this item?

Or does anyone know a link to a site where I might find a PDF?

TIA. Mike.

Radiac .... An acronym derived from the words "radioactivity, detection, indication and computation" and used as an all-encompassing term to designate various types of radiological measuring instruments or equipment. (This word is normally used as an adjective.)

NIGA = Nuclear Induced Gamma activity.

Nice pieces, but I don't know if there is a manual for that. i have never come across it, but there will be one.

Thank you, I am getting a bit bored with collecting Uniforms, smocks, berets etc, and am always looking for ABL equipment that is a bit more "Off the beaten track" so to speak.

There is a US army manual for the guide, (the circular slide rule was actually commissioned from Nestler by the US.)  but it seems to have been used outside US forces.

The US guide was "Instruction Pamphlet for Commander's Radiation Guide. AGL (1) 3-59-13M-70955."

But I cannot find it or even a PDF of it on the internet.

I left a typo in an earlier post , so here is correction....

NIGA is acronym is for either "Neutron induced Gamma Activity" or "Nuclear Indirect gamma Activity"

A facebook group where I asked the same question has come up with this.

Not exactly the same calculator, but near enough that I now understand and can use one side of the calculator, and at least part of the other side.
