Every effort should be made to meet the guidelines set out in this form as they are all good laboratory practices. If an individual occupies several of these locations, the dose from all locations should be totalled this scenario should be considered when assigning occupancy factors.
From the final column, it is reasonable to assume 110648-1, for this example, the radiation doses incurred ieo staff or the general public as a result of thyroid uptake procedures are negligible in comparison with cardiac analysis or bone scans and can be omitted from the dose estimation.
This part of ISO deals with three types of containment enclosure: The room will be at negative pressure with the surrounding area unless the room will be used as a clean or sterile room. The fume hood exhaust will not connect to other exhaust systems. Air kerma 1048-1 were converted to dose using NIST values for mass energy absorption coefficients. If the room or storage area is to be used for non-nuclear work as well, then separate 10648–1 areas will be defined for the nuclear and non-nuclear work.

For any given nuclear medicine facility, several different gamma emitting nuclear substances can be identified that are used regularly e. Where standard dimensions are not suitable, other dimensions may be chosen but the containment enclosure shall comply with this part of ISO in design principles, mounting and assembly.
To avoid interference, supply air vents will be installed away from, or directed away from, fume hoods. Air flow will always be from the area of low radiation. These key locations cover areas of occupancy of technicians NEWs and non-NEWs, including the physician in the adjoining clinic.
Containment enclosures – Part 1: If the air intake will be less than The same approach would be used for the other locations or other representative individuals. If you need help with the purchase or have any queries please email enquiries standards.
The following 5-step method for calculating dose estimates is a suggested approach only; it does not restrict the applicant from using other approaches. Table Isk summarizes the parameters required to perform the dose rate estimates for the receptionist. Please note that the selected standard is invalid. Values of exposure rate and air kerma rates are also commonly used and available in literature.
Dose estimates for veterinary nuclear medicine are very similar to dose estimates for conventional diagnostic nuclear medicine. Flooring will have a strippable coating for easier clean-up if contaminated.
ISO 10648-1:1997 (R08)
This section is to be completed only if volatile nuclear lso are to be used or stored, or if aerosols or gases are likely to be produced. Amazon Prime Music Stream millions of songs, ad-free. International Classification for Standards ICS is an international classification system for technical standards. The last two types can be mounted behind shielding or can have directly attached shielding. Fume hood exhaust ducts will contain only vertical sections. Fume hoods will not contain filters.
This Web page has been archived on the Web. Patients typically occupy several different locations over the course of the nuclear medicine is and may contribute to the dose received by a person occupying a single location e. This method is generally useful when evaluating an existing department, or when making a comparative analysis for designing a new room or department that is very similar in layout and design to an existing site.
Specific gamma ray constants are typically defined in terms of the dose rate produced e.

For example, nuclear medicine technologists are usually designated as NEWs. Poly-energetic source A source that has multiple radiation emissions of unique energies. The quantity of unsealed nuclear substance used at a single time does not exceed 50 times its corresponding ALI. Sustainable Development Goals and standardisation, how do they connect?

The fume hood will be constructed of smooth, impervious, washable, and chemical-resistant material. However, all types of procedures, total number of patients and average activities should be provided to the CNSC and those used in the assessment should be justified. This part of ISO applies to enclosures or enclosure lines intended to be used for work on: Radioactive waste storage areas within the room will be lockable, to restrict access to authorized individuals only.
Information identified as archived on the Web is for reference, research or recordkeeping purposes. Fume hood exhausts will be located on the roof as far away as possible from any air intakes, to prevent recirculation of the fume hood emissions the minimum recommended distance is Alternatives that provide an equivalent degree of safety will be reviewed.
Diagnostic nuclear medicine rooms are typically shielded using commercially available lead sheeting, with normal thicknesses varying from 0. For clean or sterile rooms, an anteroom may be required.

Additional information may be requested by the CNSC after the initial assessment. DCF Dose conversion factor; the committed effective dose in Sv, per unit activity in Bq, delivered by a given radionuclide of a given form. Occupancy Factor The fraction of total time during which a radiation field is present at a particular location, for which an individual is present at that location. Visit our Help Pages.
