Whereas some mobile teams are staffed with one medical assistant and nurse, other mobile teams may be staffed with medical specialists providing more complex diagnostic and treatment services, such as, for example, lung examinations by fluoroscopy. While many medical assistants and nurses in predominantly indigenous areas are indigenous, most doctors are not. Although indigenous peoples rarely face language problems in their communication with doctors, there is a need for doctors to have better knowledge of the indigenous cultures.3 Physicians training at medical universities are neither exposed to course on "northern medicine" nor trained to work with indigenous peoples. Indigenous northerners in the Russian Federation live in regions with rich natural resources, among them oil, gas and gold, and extractive industries contribute to ecological destruction.
