Clean the swimming pool by a conventional method. Cleaning using tap water will
be acceptable, however, to be safe, the water would be better off discharging after
checking the radioactivity concentration.
(10) Clearance
(a) Check the radioactivity after the work
Check the reading of the personal dosimeter, and fill in the form, “Record 6:
Record of personal dosimeters”.
(b) Put tools and equipment used for the decontamination and generated waste
away.
Put clothes contaminated with radioactive materials in plastic bags separately
from conventional trash so that they can be stored together with those containing
the precipitate. Mark a serial number on the bag with a felt pen .
The mouth of the bags shall be twisted, folded back and closed with a banding
band. Put the bags into additional plastic bags, forming a double packing. The
outer bags shall also be twisted, folded back and closed with a banding band.
Measure the dose rate of each bag on the surface using a radiation detector. If
possible, weigh the bag (weight by the kilogram is acceptable). Write down the
results in the form, “Record 17: Dose rate measured on the surface of bags that
contains waste generated during the clearance”.
