A protective sheet should be placed between the sample and the screen to minimize the
chance of radioactive contamination (Figure 4.11).

Wet Radioactive Samples
Precautions must be taken to prevent wet samples from contaminating the imaging screen.
Wet thin samples should be completely enclosed in a heat-sealable bag and moist samples
must be covered with plastic wrap before being exposed to the imaging screen.
Caution: Direct contact of a wet sample with the imaging screen may cause irreversible
screen damage.
Caution: Alkaline denaturing gels must be neutralized before being wrapped and exposed
to the screen.
Caution: Never expose the K/Tritium screens to wet samples, even if they are covered.
