FIELD: physics.
SUBSTANCE: device for irradiating minerals has a reactor active zone, an irradiation channel, a container and extra slow neutron filter. Inside the container there are slow and resonance neutron filters. The extra slow neutron filter surrounds the container and is fitted in the irradiation zone. A gamma-quanta absorber of the reactor is placed between the container and the active zone of the reactor. A resonance neutron absorber is added to the extra slow neutron filter. The thickness of these absorbers enables to keep temperature inside the container not higher than 200°C during irradiation.
EFFECT: invention increases the possible volume of irradiated specimens and increases efficiency of modifying minerals.
