Cf-252 FTC-CFZ-431
Overview
An official document for the CF-252 source with serial number FTC-CFZ-431 provides a value for the neutron rate and CF-252 mass as of 03/19/1993.
The initial neutron rate and mass of cf-252 are stated to be
and 4.2 , respectively.4.2
would generate neutrons per second. The discrepancy between these two numbers gives a 2% error.Click here to open a table giving neutron rates and cf252 activity of the source from dates 1/2017 to 12/2029. The calculation only includes neutrons from CF-252, since all other daughter nuclei and possible impurities have a very low SF rate compared to cf-252.
