Abstract
A number of longliving and still being produced radioactive isotopes produces well measurable and not to be neglected radiation, by which, via the food chains, plant, animal and man receives a socalled natural radiation dose. Six of the most important isotopes are discussed here. The radioisotopes /sup 14/C and /sup 40/K form part of the most live-necessary elements; they pass without strong enrichment and discrimination through the food chains and form a practically constant part of the living organism. Yet by excessive fertilizing a rather higher content of potassium than necessary is present in plants. Also a higher radiation dose arises from exessive uptake of food. The isotopes of uranium /sup 238/U and radium, /sup 226/Ra, discussed here, occur everywhere in the soil, but locally in very high amounts. They migrate for a very small part into plant and animal, sometimes occur in vegetable food as part of soil particles. Other important isotopes of the uranium families are radioactive lead, /sup 21/0Pb, and polonium, /sup 210/Po, which can be dispersed to a much greater amount than the other isotopes: in the form of the gaseous intermediate product radon, here the isotope /sup 222/Rn. /sup 210/Pb and /sup 210/Po are finally
