Introduction
We are pleased that you are interested in learning more about x‐ray technology and how the
    installation of an x‐ray system can help you protect your brand and ultimately protect the
    consumer.
Food safety and quality is always a major component of a food manufacturer’s vision statement.
    Producing low quality, tainted products can and will be the demise of a food processor and could
    lead to expensive lawsuits and recalls when contaminants are found within a product. Packaging
    anomalies can create many consumer complaints and result in the loss of brand integrity and
    profitability. There are various technologies available to protect your interests from various
    consumer claims and many technologies are complements to each other. A fully managed food
    safety plan includes the use of various technologies under the watchful eye of a solid HACCP or
    quality control plan managed by the quality control team and ultimately understood and
    accepted by the entire organization.

These techniques allow the analysis and detection of various densities, shapes, sizes and grayscales to
pinpoint low density contaminants, small high density contaminants, small wires, large conglomerates and
other anomalies such as missing items, underweight conditions and mis‐packaged products. Additional
techniques are used to look for small wires hidden in products that are particulate or variable in density.

    CABINET X‐RAY FAQs
Q2: What are other common names for cabinet x‐ray systems?
A2: Other common names for cabinet x‐ray systems are X‐ray Inspection Systems, X‐ray Screening Systems, X‐ray Security Systems, and Baggage X‐ray
      Systems. The words inspection, screening, security, and baggage might also be used interchangeably with or in addition to the description of a
      cabinet x‐ray system.
Q3: Which agency has responsibility for assuring that manufacturers produce cabinet x‐ray systems that do not pose a radiation safety hazard?
A3: The US Food and Drug Administration (FDA) has responsibility for assuring manufacturers produce cabinet x‐ray systems that do not pose a radiation
      safety hazard. For most electronic products that emit radiation, safety regulation is divided between FDA and state regulatory agencies. Typically,
      FDA regulates the manufacture of the products and the states regulate the use of the products. For further information on FDA regulations that
      apply to manufacturers of electronic products that emit radiation (such as a cabinet x‐ray system) see the FDA web site
      (http://www.fda.gov/cdrh/comp/eprc.html).
Q4: What other Federal Agencies are involved in radiation safety when the source of the radiation is an x‐ray
product?
A4: The US Environmental Protection Agency (EPA) is responsible for issuing general radiation guidance to Federal Agencies. Additionally, basic
      information about radiation is available on the EPA web site (http://www.epa.gov/radiation/index.html). The US Occupational Health and Safety
      Administration (OSHA) has regulations on worker safety from radiation in the workplace (http://www.osha.gov).
Q5: Is it safe to stand or walk near a cabinet x‐ray system while it is producing x‐rays?
A5: Yes. Manufacturers are required to certify that their products meet the Federal radiation safety performance standard for cabinet x‐ray systems.
       Specifically, the standard requires that the radiation emitted from a cabinet x‐ray system not exceed an exposure of 0.5 milliroentgens in one hour
       at any point five centimeters from the external surface. Most cabinet x‐ray systems emit less than this limit. In addition, the standard also requires
       safety features that include warning lights, warning labels, and interlocks. For comparison, the average person in the United States receives a
       dose of about 360 millirem of radiation per year from background radiation. (Note: 1 milliroentgen of exposure to x‐rays will result in
       approximately 1 millirem of dose. These terms are defined later in this document.) Background radiation is radiation that is always present in the
       environment. Eighty percent of that exposure comes from natural sources: radon gas, the human body, outer space, rocks, and soil. The remaining
       20 percent comes from man‐made radiation sources, primarily medical x rays. For additional information on certification and labeling, see Title 21
       Code of Federal Regulations (CFR) 1010. For the details of the cabinet x‐ray performance standard see Title 21 CFR 1020.40. For further
       information on recommended limits of radiation exposure, we recommend the National Council on Radiation Protection and Measurements
       Report 116, Limitation of Exposure to Ionizing Radiation (1993).

   CABINET X‐RAY FAQs
Q6: Is it safe for pregnant women to stand or walk near a cabinet x‐ray system while it is producing x‐rays?
A6: Yes. The limit on radiation emission established by the performance standard is sufficiently restrictive that
     there is no additional hazard for specific populations such as children or pregnant women.
Q7: Are the operators of cabinet x‐ray systems required to wear a “radiation badge”?
A7: Personnel monitoring equipment is not required by Federal regulation for operators of cabinet x‐ray
     systems. It is possible that some state regulations or the policies of the operators’ employer require use
     of personnel monitoring equipment. Personnel monitoring equipment means devices designed to be
     worn or carried by an individual for the purrpose of measuring a radiation dose received (e.g. film
     badges, pocket dosimeters, film rings, etc.). For more information, please see the OSHA regulations
     found in Title 29 CFR 1910.1096(d) Precautionary procedures and personal monitoring and contact OSHA.
     The OSHA regulations are based on the amount of radiation that a worker can receive in a specific area
     from all radiation sources. The Federal limit on cabinet x‐ray system emissions ensures the maximum
     possible exposure from cabinet x‐ray systems in the workplace will always fall below the minimum
     threshold where personnel monitoring might be required.
