An Analysis of Residual Radiation in Thoriated Camera Lenses
The usage of the naturally occurring radioactive isotope thorium-232 in older camera lenses was implemented to provide better optical properties and a cheaper production. In this thesis, the resulting radioactivity in camera objectives containing such lenses is studied via gamma spectroscopy. A numb...
