(3) Remove fallen leaves and other objects accumulated on the bottom of the
swimming pool
• Record 9: Dose rate measured on the surface of bags that contain fallen leaves,
etc. collected from the pool
(4) Pump the pool water into 1 ton plastic tanks for the treatment using zeolite
(first treatment)
• Record 10: Work record using 1 ton plastic tanks (1st treatment)
(5) Discharge the supernatant, while leaving precipitate
• Record 11: Radioactivity concentration in the water after filtration using a
filter with a filter cloth
(6) Treat the precipitate left on the bottom of the 1 ton plastic tanks
(7) Treat water and precipitate left in the pool (2nd and 3rd treatment)
• Record 12: Radioactivity concentration in the pool water and precipitate
before the 2nd treatment
• Record 13: Radioactivity concentration in the pool water and precipitate
after the 2nd treatment
• Record 14: Radioactivity concentration in the supernatant before the 3rd
treatment
• Record 15: Radioactivity concentration in the water after filtration with a
filter cloth
(8) Bag in the sludge after filtrating the precipitate
• Record 16: Dose rate measured on the surface of bags that contains the filter
sludge
(9) Clean the swimming pool wall
(10) Clearance
• Record 17: Dose rate measured on the surface of bags that contains waste
generated during the clearance
• Record 18: Ambient dose rate at the temporary storage of the waste
