FIELD: atomic physics.
SUBSTANCE: invention relates to acceleration engineering. The isotope production system comprises a cyclotron having a magnet yoke that surrounds an acceleration chamber. The cyclotron is configured to direct a particle beam from the acceleration chamber through the magnet yoke. The isotope production system also includes a target system that is located near the magnet yoke. The target system is configured to hold a target material and includes a radiation shield that extends between the magnet yoke and the target location. The radiation shield has a size and a shape which enables to attenuate gamma rays and neutron radiation emitted from the target material towards the magnet yoke. The isotope production system also includes a beam passage that extends from the acceleration chamber to the target location. The beam passage is at least partially formed by the magnet yoke and the radiation shield of the target system.
EFFECT: reduced radiation effect.
