Neutron therapy apparatus |
摘要 |
The portion of the shield of a neutron radiation apparatus which is situated nearest to the neutron source is made of tungsten. As a result, a commonly used outer shielding layer consisting of a heavy metal can be dispensed with, so that improved shielding and a substantial saving as regards weight are combined.
