Document Type and Number:
WIPO Patent Application WO/2011/105035
Kind Code:
A2
Abstract:
A radioactive ray generating apparatus includes a second shielding member, a target, and a first shielding member, which are sequentially disposed from an electron emission source side. A shortest distance from a maximum radiation intensity portion of the target to the first shielding member is shorter than a shortest distance from the maximum radiation intensity portion of the target to the second shielding member.
