<strong>JAEA</strong>-<strong>Testing</strong> <strong>2011</strong>-007<br />
Clean the swimming pool by a conventional method. Cleaning using tap water will<br />
be acceptable, however, to be safe, the water would be better off discharging after<br />
checking the radioactivity concentration.<br />
(10) Clearance<br />
(a) Check the radioactivity after the work<br />
Check the reading of the personal dosimeter, and fill in the form, “Record 6:<br />
Record of personal dosimeters”.<br />
(b) Put tools and equipment used for the decontamination and generated waste<br />
away.<br />
Put clothes contaminated with radioactive materials in plastic bags separately<br />
from conventional trash so that they can be stored together with those containing<br />
the precipitate. Mark a serial number on the bag with a felt pen .<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 />
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 17: Dose rate measured on the surface of bags that<br />
contains waste generated during the clearance”.<br />
