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