6.Measurement results

  Please come to the center to get your measurement results.

We also ask you to take your soil samples back with you after the measurement.


1.Sample Preparation

  Food sample preparation
  Foodstuff should be cut into small pieces of about 5mm size and brought in clean
  packages (in plastic bags, plastic containers, etc.) At least 1 liter of food or liquid
  sample is required for measurement.

  Please note that when the amount of samples is not enough, the results will be less
  precise. If you are not able to bring the required amount of samples please consult us.

  We ask you to remove unnecessary parts of food such as fruit skin or internal organs
  before cutting the foodstuff into small pieces.

  Soil Sample Preparation
  At least one liter of soil sample is required for the measurement.

  You should make your sample from soil gathered from five different points in the land to
  be measured. One point should be the center of the land and the other four should be
  from the center of each quarter section of the land.

  You should get vertically some 15 cm thick block of soil, and each portion should have
  the same dimension (for example: 10㎠.) Mix the five portions well into one sample to
  make it more than one litter.

  Special measurements may require more than this amount.

  Please avoid taking soil samples right after rain.
  It’s preferable that you gather soil samples about one week before the measurement day.

2.Food sample data

  You should fill out specific data of food samples in the “Soil Radiation Measurement
  Request Form”.
  Please bring the necessary information and your personal seal with you.

3.Car Park

  There is limited parking space at the center. Please use nearby pay parking lots when this
  parking lot is full.
