(3) Remove fallen leaves and other objects accumulated on the bottom of the
swimming pool
Scoop up large items in the precipitate such as fallen leaves accumulated on the
bottom using fishing net or other tools. The scooped items such as fallen leaves
shall be collected in a basket to drain water. Collect the water passing through the
basket in a tray and return it to the pool.
Put the drained fallen leaves in plastic bags with a serial number.
The mouth of the bags shall be twisted, folded back and closed with a banding
band. The bags shall be put into additional plastic bags, forming a double packing.
The outer bags shall also be twisted, folded back and closed with a banding band.
Measure the dose rate of each bag at the surface using a radiation detector. If
possible, weigh the bag (weight by the kilogram is acceptable). Write down the
results in the form, “Record 9: Dose rate measured on the surface of bags that
contain fallen leaves, etc. collected from the pool”.
