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