How do you perform soil testing for radiation?

The first thing you need to do is get a trowel and bucket, to take samples of your soil. You need to capture several samples from different locations around your lot. Most labs will want samples from 3 inches deep. Dig a handful of soil using a trowel and put it in a bucket. Make sure that your trowel does not have any fertilizer residue to avoid contamination of the sample. Then, mix all the samples together in the bucket and measure up 1-2 cups of soil to be submitted.
