Appendix K
CALCULATIONS
This appendix provides a single reference location for CBRN hazard prediction-
related calculations.
Downwind travel distance:
d1 = u1 * t1
d2 = 2u2
d3 = 2u3
Total Downwind Distance:
DA = d1 + d2 + d3
Leading and Trailing Edge:
DL = 1.5 * DA (Leading Edge, in KM)
DT = 0.5 * DA (Training Edge, in KM)
Initial Hazard Area (BIO only):
H1 = A + d1 or A + (u1 * t1 )
The following are calculations contained in Appendix G for nuclear contamination
avoidance TTP:
Polar Plot Method for Determining GZ:
0.35 kmps x time(s) = Distance to GZ, in km
M4A1 Calculator:
Covert degrees to mils (17.8 x degrees = mils)
Yield Estimation:
Yield 1 + yield 2 = sum yield / 2 = average yield
Time of Arrival of Fallout:
distance from GZ (km)
= time of arrival
effective wind speed in (kph)

Normalizing Factor (NF)
R1 = NF x R2
NF = (T2)n
Overall Correction Factor (OCF):

NOTE: If R1 is the normalized dose rate reading at H+1, then t1 will always be 1.
Therefore, the equation can be set up as: t2 = R1 / R2 This equation can only be utilized
per the validity time for the decay rate.
