#OBJECT INFORMATION
#------------------
#OBJECT NAME
#DENSITY [g/cm^3]
#EFFECTIVE BUILDUP FACTOR : if all 1.0’s then calculation neglects this effect; values taken from nucleonica website
#LINEAR ATTENUATION COEFFICIENT, mu/rho [cm^2/g], taken from NIST website tables (using linear interpolation when necessary)
# Lines beginning with the character “#” will be ignored by the script.
# Lines beginning with the character “@” will use the first word as dictionary keys.
# Lines beginning with the character “$” will use the first word in the line as dictionary sub-keys.
