Nuclear Chicago C-14 Slide Rule (1960s)
|The C-14 slide rule was distributed by the Nuclear Chicago Corporation, probably in the early 1960s given the copyright date of 1959.|
The slide rule had several functions. First, and most important, it indicated the product code and price for a wide variety of C-14 labeled compounds. Second, for a specified count rate and dead time, it indicated the percent of the counts that would be lost. Finally, it indicated the % error due to counting statistics for a specified count rate and count time.
