Problems solved by technology

Moreover, the high energy radiation dissipates a large amount of energy into the target, i.e. the envelope and the microbial material, causing heating of the microbial material as well as the envelope
This heating increases the likelihood of envelope rupture and spillage of microbial material

example

[0062] Anthrax spores contained in a paper container having a density of from about 0.3 g / ml to about 0.56 g / ml are irradiated with an electron beam of 200 keV to 500 keV generated by the radiation generating device 10 . The electron beam has a current of about 1 amp to 100 amps and a diameter of about 1 cm. The pulse duration is about 5 nanoseconds. The distance to microbial contamination is from about 0.1 mm to about 2.5 mm. The radiation generating device 10 generates radiation directed at anthrax contained in a paper container. The amount of radiation absorbed is determined by the following formula:

[0063] D=EIt / m=EIt / ρ1S

[0064] where E is the kinetic energy in joules, I is the electron beam current, t is the pulse duration, m is the mass of the object to be irradiated, ρ is the density of the spores, and l is the thickness of the spores (up to the penetration depth of the electron beam) , S is the cross-sectional area of ​​anthrax spores exposed to the electron be...

Abstract

The present invention provides a portable radiation generating device for generating high energy electron beam radiation and X-rays from a low voltage power source such as a battery (42). The pulse high voltage generator (40) includes a power supply (42) and a Tesla transformer (41). The Tesla transformer has at least one first capacitor (44), a primary coil (46), a secondary coil (48), and at least one second capacitor (50). The at least one second capacitor is disposed axially within the secondary coil. A control system (60) is connected to the pulsed high voltage generator (40) for selectively controlling the energy transfer from the pulsed high voltage generator (40) to the radiation generating device (22). The radiation generating means are used to generate pulses of electrons and X-rays. Each pulse has a duration of approximately 100 nanoseconds. The electrons and X-rays generated by the radiation generating device can be used to inactivate microbial contaminants or irradiate various materials.

Description

technical field [0001] The present invention relates to methods and radiation generating devices for generating radiation, and more particularly to radiation generating devices for inactivating microbial contaminants. Background technique [0002] The U.S. Postal Service has been used as a means of delivering anthrax spores. Postal services and other courier services are likely to be used to deliver other biological products. [0003] Finely divided spores penetrate paper envelopes more easily. During normal mail handling, anthrax spores and other biological material can leak from envelopes, contaminating the surfaces of mail handling equipment, adjacent floors and equipment, the exterior of carrier envelopes, and the surfaces of other envelopes. [0004] Therefore, there is a need for an apparatus for immediately on-site disinfection of suspicious mail and other mail and processing equipment that the suspicious mail has come into contact with. [0005] Liquid and spray d...
