En la naturaleza, el radio se encuentra en bajas concentraciones en el suelo, el agua, las rocas, el carb\u00f3n, las plantas y los alimentos. Con el tiempo, el radio se desintegra y libera radio-226, radio-228 y radio-224. Si bien la vida media del radio-226 es muy larga, de 1600 a\u00f1os, la del radio-228 es de tan solo 6,7 a\u00f1os y la del radio-224 es a\u00fan m\u00e1s corta, de 3,5 d\u00edas.<\/p><p>A medida que los diferentes is\u00f3topos se descomponen, pueden ingresar al cuerpo a trav\u00e9s de la ingesta de alimentos, agua potable o absorci\u00f3n cut\u00e1nea.
