Radiation safety attached to radioactive sources management - additional aspects

Radiation sources are used in many scientific areas. Safety management requirements are determined for them with guarantee of the international and national dose limits unexceeding. As a rule, such dose limits are being developed concerning the type, energy, and flux of main radiation. Lack of knowledge of these attendant radiations can put personnel in danger. The study of the attendant neutron and gamma-radiations for plutonium 128 alpha sources was made.
