Abstract
A system and method for utilizing a radiation source for irradiating a product, the system including an radiation reflector comprised of a low Z, high density material. The reflector is positioned to receive radiation penetrating and exiting the product, and the reflector reflects the radiation back to the product to provide additional irradiation energy to the product.
Claims12
A system for irradiating a product with a source of radiation comprising, in combination,
- a) a source providing radiation to penetrate and irradiate the product;
- some of the radiation exiting the product;
- and
- b) a reflector of a high density, low Z material positioned to receive radiation exiting the product and to reflect back some portion of the radiation exiting the product to re-irradiate said product.
A method of irradiating a selected product comprising, in combination,
- a) directing radiation of sufficient energy to cause some of said radiation to penetrate and exit the product;
- b) positioning a reflector of a selected high density, low Z material at least three quarters inch thick to receive radiation exiting the product and to reflect said radiation;
- and
- c) directing the reflected radiation back to irradiate said product.
A system for irradiating with X-rays a product which product has top, bottom and sides surfaces comprising, in combination,
- a) a source for providing X-rays directed to irradiate the top surface of the product;
- b) said source of X-rays providing X-rays suitable for penetrating at least 4 cms of water equivalent product;
- c) a reflector of a high density, low Z material positioned to receive X-rays exiting the product and to reflect back a major portion of the X-rays exiting the product to re-irradiate said product;
- d) said reflector being of boron carbide and being of a thickness of at least 10 cms in thickness,
- e) said reflector being configured to reflect X-rays back to the sides of the product as well as to the bottom of the product;
- and
- f) said reflector being positioned adjacent the bottom surface and side surfaces.
