The Nuclearule was originally produced by the Nuclear Instrument & Chemical Corp., in 1949 or 1950. It was described then as follows "The "Nuclearule" calculator is a special circular slide rule with scales for use in radioactivity calculations. It can be used for computation of count rate, statistical error, coincidence loss, sample activity vs half-life, and radiation flux after passage through absorbers."
From the General Description in the operating manual: "One side of the rule, called Side I, gives the relationships between the register reading COUNTS of a scaler, the SCALE FACTOR of the scaler, the elapsed TIME in making the count, the COUNT RATE, and an approximation of the various statistical errors. The other side of the Rule, called Side II, gives (1) the relationships between COUNT RATE, RESOLUTION TIME, and COINCIDENCE LOSS; and (2) the ACTIVITY of a source as a function of the number of HALF LIVES or as a function of the number of half thicknesses of absorbers." The above photo shows Side II.

Nuclear Slide Rules

Have no idea what it might be worth. Looks like eBay item and see where it goes. Is kind of timely.

1. Comes with org. case and instructions.

Very good condition too.
case and all is 6" by 6".

2. Seen a lot of similar ones (not nuclear)

engineers had in the aircraft industry, today they rely on calculators more than anything, not to say they
don't collect older stuff, good luck. Feeling better, all healed up?

3. My dad has a patient on one kind of like this

for the dairy industry to figure out butterfat in milk.
Most of the hits on DuckDuckGo are in museums.

5. I saw that and thought how great Bill Boards

in Red States could be. Have to use Reps focus groups to see what might catch their attention.

I think there will be lots of ups and downs in the next few years. Just have to GOTV for the midterms now. I see a lot of them are already planning what crazy s**t they do when they win the House and Senate. Bats**t nuts.

6. If the DNC doesn't do something really stupid we should control both Houses

With Jan 6th Committee coming out with televised hearings and IQ4.5 demanding loyalty from everyone
while attacking those who whisper one thing he doesn't like should keep repugs disorganized & ineffective
at the ballot box.

7. Looks more and more like Putin is

Messing up the plans. Might happen. No telling what might happen.
