|Long Waves (365nm): || Green ||Weak||Short Waves (254 nm): || Green ||Weak|
Phosphorescence (in the common meaning of the term) seen by naked eye:
No phosphorescence seen by naked eye whatever the type of UV
Usually cited as non-fluorescent in the specialized litterature over uranium minerals, but cited as fluorescent in Henkel's book; possibly a misidentification or an impure specimen.
