Indoor Gardening
If you are concerned that your garden will be subjected to rain
containing radioactive material, and you are able, a greenhouse or
indoor gardening space will protect your fruits and veggies. Make sure
to use uncontaminated soil by treating it with one of the clays
discussed earlier, rock dust, and/or baking soda before planting.
These soil treatments will be discussed in the next section titled
“Treating the soil.”
