(c) Measure ambient dose rates at and around the work place to make a dose map<br />
before starting decontamination procedures<br />
Survey ambient dose rates around the swimming pool, at and around the drain<br />
gutter and outlet to external waterway, along work flow lines and temporary<br />
storage of radioactive waste at the height of 100 cm to make a map allowing<br />
knowing dose rate at anywhere you want.<br />
The surveys are required for determining the change in dose rates before and<br />
after the procedures, and confirming that no radioactive material is taken away<br />
from the work place, and that the dose rate has not been increased due to water<br />
discharged after the treatment.<br />
Utilize any available site layout drawing of the school. If not available, prepare a<br />
simple layout drawing that shows location of measurement points relative to the<br />
school buildings and facilities.<br />
Use the form, “Record 2: Ambient dose rate map of the swimming pool and pool<br />
side before the procedures” to write down the survey results for the swimming<br />
pool and the pool side.<br />
Use the form “Record 3: Ambient dose rate map in the work area (before the<br />
procedures)” to write down the survey results for outlet to external waterway,<br />
along work flow lines and temporary storage of radioactive wastes.<br />
