Abstract
A system for protecting sealed or closed packaging means from tampering or nauthorized opening. A source of radiation cannot affect radiation sensors until the packaging means has been penetrated or tampered with. Then the radiation sensors set off a visual alarm, an audible alarm, or otherwise indicate that there has been an unauthorized penetration.
Claims10
Apparatus for sensing penetration of a container, comprising radiation-emitting material substantially on all sides of said container, a radiation shielding rupturable member inside of said radiation-emitting material, and radiation sensing means inside of said radiation shielding member to sense radiation emissions or leakage if said radiation shielding member should be penetrated;
- said radiation shielding member completely shielding said radiation sensing means from radiation prior to rupturing of said radiation shielding member, so that only upon rupturing of said radiation shielding member the radiation emitted by said radiation-emitting material reaches said radiation-sensing means.
Apparatus for sensing penetration of a container comprising radiation-emitting material substantially on all sides of the container, a radiation shielding member inside of said radiation-emitting material, radiation sensing means inside of said radiation shielding member to sense radiation emissions or leakage if said shielding member should be penetrated, means to activate said sensing means from a coded signal transmitted from outside of said container, and means to transmit such coded signal to said sensing means.
