Equation of Azizova et al for Correlating the Absolute Lymphocyte Count on Day 3 After an Exposure and the Radiation Dose

Description

Azizova et al developed an equation correlating the absolute lymphocyte count on the third day following a radiation exposure with the acute dose. The authors are from Southern Urals Biophysics Institute, the University of Pittsburgh, Mayak Production Association, and the University of California Davis.


Parameters:

(1) absolute lymphocyte count on day 3 after a radiation exposure

(2) acute radiation dose in Gy

 

absolute lymphocyte count in 10^9/L =

= 1.12 - (0.61 * LOG10(absorbed dose in Gy))

 

If this is rearranged:

 

absorbed dose in Gy =

= 10^((1.12 - (absolute lymphocyte count in 10^9/L)) / 0.61) =

= 10^(1.836 - (1.639 * (absolute lymphocyte count)))
