Radioactive Cesium is rising in topsoil, grass, and strawberries.

UCB Food Chain Sampling Results

Radionuclides, once deposited by rainwater or air onto the ground, will find their way through the ecosystem. We are already tracking its path from rainwater to creek runoff to tap water, but we would also like to monitor how much these isotopes that make their way into our food. For example, how much gets taken up by the grass and eventually winds up in our milk?

We have been collecting produce that is as local as possible to test for the radioactive isotopes. We might expect different kinds of plants to take up different quantities of cesium and iodine, so we are trying to measure as many different plants and fruits as we are able to. So far, we have measured grass, wild mushrooms, spinach, strawberries, cilantro, kale, and arugula. We have also measured local topsoil.  CHARTS
