Correction factors needed for determination of dose rate in Protocol 1.

Correction Factor	Explanation
N_κ	Air kerma calibration factor
[(μ_en/ρ)^Wair]water	Ration of mass energy absorption coefficients of water to air; approximately 1.05
P_q,Cham	Correction accounting for chamber stem affecting photon fluence perterbation by chamber; approximately 1.022
P_sheath	Correction accounting for sheath protecting ionization chamber; value of 1, as chamber is waterproof
P_pol	Correction factor accounting for polarity; determined in Protocol 1
P_ion	Correction factor accounting for ion recombination; determined in Protocol 1
P_Tp	Correction factor acocunting for temerpature and pressure on day of experiment; determined in Protocol 1
