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 [math]10^{7}s^{-1}[/math] and 4.2[math]\mu g[/math], respectively.

4.2 [math]\mu g[/math] would generate [math]9.67 \times 10^{6}[/math] neutrons per second. The discrepancy between these two numbers gives a 2% error.
