(8) Bag in the sludge after filtrating the precipitate<br />
Bag in the sludge left on the filter cloth (sludge) after binding both ends of the<br />
sheet as shown in the photo. Mark a number with a felt pen on the surface of the<br />
bag to identify which sheet was used for the filtering.<br />
The mouth of the bags shall be twisted, folded back and closed with a banding<br />
band. Put the bags into additional plastic bags, forming a double packing. The<br />
outer bags shall also be twisted, folded back and closed with a banding band.<br />
Precipitate after filtration (sludge) Bind both ends of the sheet.<br />
For both plastic bags, the mouth shall be<br />
twisted, folded back and closed with a<br />
banding band.<br />
Measure the dose rate of each bag on the surface using a radiation detector. If<br />
possible, weigh the bag (weight by the kilogram is acceptable). Write down the<br />
results in the form, “Record 16: Dose rate measured on the surface of bags that<br />
contains the sludge”.<br />
A tentative storage area during the work and the place for the temporary storage<br />
of the sludge needs to be selected after careful consideration, since the sludge<br />
contains relatively large quantity of radioactive materials.<br />

Put the sludge together with the filter<br />
sheet into a plastic bag, which is again<br />
put into a plastic bag.
