a person giving his own blood for transfusion, or tissue (for example, skin) or an organ (for example, a kidney) for transplantation in a patient (the recipient). At the present stage of science the most widely found form of donation is blood donation. In the USSR donation is a voluntary act. Any healthy (according to a special medical examination), physically mature person 18 years of age and older can become a donor. The giving of blood is harmless for the donor. The health of the donor is protected, and in the USSR the donors have benefits. They are permitted to leave work with pay in order to give blood, and after giving blood they receive a day off with pay from the institution where they are employed. Donors are the first to receive permits to stay at sanatoriums and rest homes. The Executive Committee of the Red Cross and Red Crescent has established an award for donors, the badge Honorary Donor of the USSR.
