Testing lenses for radiation : Yashica Auto Yashinon-DS-M 50mm F1.4 lens.

Despite being well known for being radioactive, the results we see from this lens is surprising. We also spend quite a lot of money to get the results you see in the video.

Dosimeter: Este Air Counter S gamma radiation detector.
Mazur Instruments PRM-8000.
SI Instruments Radiation Alert Inspector+.

After background radiation is normalized, the lens is placed 1cm below the detector's sensor. The lens is then reversed to see which side emits more radiation.
