xripl.tubeTransmission.transmission(density, opacity, length)

Calculates the transmission through a uniform material of given density, opacity, and length.

densityfloat

Mass density of the material in grams per cubic centimeter.

opacityfloat

Opacity of the material (also known as mass attenuation coefficinet) in squared centimeters per gram.

lengthfloat

Attenuation length through the material in centimeters.
