(1) Measure ambient dose rate at the condition without pool water<br />
(a) Measure the ambient dose rate at the bottom of the swimming pool and pool<br />
side.<br />
Survey ambient dose rates at the same measurement points as those before<br />
starting the work (Record 2: Ambient dose rate map of the swimming pool and<br />
pool side before the work)<br />
Measurement points are at four corners and the center, in principle, of the bottom<br />
of the swimming pool. Add locations where drain water is collected such as drain<br />
port as measurement points.<br />
Write down the measurement results in the form, “Record 19: Ambient dose rate<br />
map at the pool and pool side”.<br />
(b) Survey ambient dose rate at the places used for the work<br />
Survey ambient dose rate at the same measurement points as those in the<br />
swimming pool, outlet to external water way, along work flow lines, temporary<br />
storage of waste surveyed before starting the procedures, and write down the<br />
measurement results in the form, “Record 20: Ambient dose rate map in the work<br />
area (after the work)”.<br />
