There are many ways of radionuclide migration in the environment. The consequence of such processes is pollution of soil, water, trees and plants as well as irradiation of people and animals.
As for the pollution of plants, this happens because of their absorption of radioactive isotope contained in soil and water.
Different plants are characterized by different ability to accumulate radionuclides. Plants that need a lot of moisture accumulate radionuclides in especially large quantities. As for crops, the largest quantity of radionuclides is in beans. Corns and roots accumulate less radionuclides. Potatoes contain even less. Among berries, blueberries and cranberries accumulate the largest quantity of radionuclides; ashberries and viburnum accumulate less. Radioactive substances in wood are concentrated mostly in the outer layers therefore dressed trunks should be used for household purposes. One should not use branches, especially those of the conifers.
Herding cattle on radiation-polluted herbage leads to the increase of radionuclides in milk and meat. Since self-made products are mostly consumed in rural areas, the probability of uncontrolled accumulation of radiation in the human organism increases. Lack of sanitary-epidemiological control over such products escalates the threat.
Another way a person can receive an extra radiation dose is living in houses and apartments built from polluted construction materials. Be sure to check for radiation safety those materials that are used for Your houses or apartments.
Your own car can also be the source of radiation threat for Your family and You, so you would want to make sure it is radiation safe before buying it.
