Embodiment Construction

[0035] The invention describes a device and a method for simulating the radiation dose of a product in an irradiation chamber as the product passes through the irradiation chamber. It will be apparent, however, to one skilled in the art that the present invention may be practiced without some or all of the following specific details. In other instances, well known process operations have not been described in detail in order not to obscure the present invention.

[0036] Embodiments of the present invention provide a method for quickly simulating a process and accurately predicting the expected dosage in any given product plan. By monitoring and reporting any number of locations well in advance of actual processing, the present invention allows the dispatcher to efficiently grasp the dosage error for each case in each batch of product in the production plan. In one embodiment, the geometry of the irradiation chamber, the composition of the irradiated product and the dosimetry...

Abstract

A method for determining dosages received by a product to be exposed to a treatment source at least one defined location from the treatment source. One exemplary method includes defining a point on the product (Fig.3, item 138). Then, fixed zones and variable zones are defined. Next, pre-calculated lengths between the point on the product and the treatment source are identified at each of the at least one defined location (Fig.4, item 158) Then, a dosage of treatment to be received by the point on the product at each of the at least one defined location is calculated (Fig.4, item 160), wherein the calculation uses the pre-calculated lengths. An apparatus for exposing a product to a treatment and a treatment system are also provided.

Description

technical field [0001] The present invention generally relates to methods and devices for predicting radiation doses, and more particularly to simulating the total radiation dose of products subjected to multi-point irradiation in an irradiation chamber. Background technique [0002] Many man-made products, including medical devices and various accessories, pharmaceutical or biotechnology materials, food, etc., need to be irradiated with radiant energy. This irradiation is usually used to reduce the number of microorganisms and bacteria to acceptable levels, or to change the characteristics of the product or its materials. This irradiation process, known as "sterilization" or "irradiation," typically involves exposing the product to gamma rays, X-rays, or other radiation sources for a predetermined period of time to achieve the desired result. This result is expressed as a dose, usually in Kilograys or Megarads, and is measured at one or more locations on and / or in the prod...
