Valid Buy this standard. Assessing the doses received by every individual from every possible source is impractical, so the evaluation may be simplified by evaluating the proximity, frequency, and duration of exposure for persons in each group to establish the most exposed persons.

International Classification for Standards ICS is an international classification system for technical standards. An alarm, either visual or audible, will be present to indicate reduced air flow. The standard is now in your shopping cart. Rooms will have sufficient counter and floor space to allow people to work safely.
Skip to main content Skip to footer. Carpeting will not be used. The fume hood will be constructed of smooth, impervious, washable, and chemical-resistant material. If the countertop abuts a wall, it will either be coved or have a back-splash against the wall.
This time has been divided into:. The room will be at negative pressure with the surrounding area unless the room will be used as a clean or sterile room.
New data and revision of the model recommend higher dose coefficient.
In such cases, the use of lead may be impractical because of weight and structural considerations. Shopping cart Close cart 0, foreach: Each fume hood will have a continuous monitoring device for proper functioning of the hood. Examples of various seals available and the assembly of containment enclosures are shown in annexes A and B. Read more about SIS Subscriptions. Although we endeavour to maintain an up-to-date catalogue, on occasion we may not have the latest version of a document, including where it has not yet been provided through an international feed.
Would you like to tell us about a lower price? For all other room classifications, future additional rooms or renovations require submission of all pertinent information and it is recommended that a completed DAF be included. Other locations may also need to be considered—the locations used in this example are for illustrative purposes.
Dose estimates will only give a reasonable representation of potential exposures if the parameters are examined carefully to ensure they properly characterize the design and operation of the facility. An accessible area will be designated to store materials and equipment used for decontamination and monitoring spill kits, survey meters where required, contamination meters where required.
When appropriate, shielding will be incorporated into the structure of the room. Either all joints in the flooring material will be sealed, or the flooring will be a one-piece design.

Occupancy Factor The fraction isk total time during which a radiation field is present at a particular location, for which an individual is present at that location. The quantity of unsealed nuclear substance used at a single time exceeds times its corresponding ALI.
Drains from the room will be identified on plans supplied to maintenance personnel. See our Returns Policy. Only patients undergoing studies may consume food or drink in the nuclear medicine rooms.
Flooring will be coved up walls and cabinets to prevent spills from penetrating underneath them. High, Containment, Nuclear Medicine, any room associated with veterinary nuclear medicine.
Food and drink preparation, use, and storage areas will not be present in the room unless required as part of a nuclear medicine procedure. A separate form should be completed for each room unless they are to be of similar design and function and of the same classification. A DAF should be completed for any new construction or major renovation such as demolishing walls or installing new fumehoods; for additional information, contact a CNSC licensing specialist and enclosed with the new application or a request for amendment.
Description of the work to be carried out in the room: Visit our Help Pages. Occupancy Summary View Table.

Fume hood exhaust ducts will be constructed of corrosion-resistant material and all joints will be smoothly finished and sealed.
To begin, it must be determined who is exposed to radiation as a consequence of the operation of the nuclear medicine department. As part of the licence application, applicants must submit the proposed design of the room in which unsealed nuclear substances will be used. Laboratories having different designations i. Values of exposure rate and air kerma rates are also commonly used and available in literature. If horizontal sections are to be used, detailed information will be submitted to show how collection of condensates or liquids coming in from the discharge point will be limited; horizontal ducts will slope at least 2.

The choice of shielding materials is ultimately left to the licensee. Any proposed variation from the guidelines should be supported by additional information to demonstrate, to the satisfaction of CNSC staff, that the guideline is not applicable due to the nature of the proposed activities, or that the guideline is addressed by alternative measures that provide an equivalent degree of safety. It is unlikely that all of the nuclear substances will be used or will contribute significantly to the annual dose at a particular location.
Design principles Article no: Where possible, an emergency shower will be provided 10648- close proximity to the room, for use in the event of major personnel contamination.
The purpose of this section is to provide guidance on how to determine and demonstrate that radiation dose estimates are ALARA prior to operations. 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.
Iao room will be equipped with lockable doors that will 106488-1 closed and 110648-1 whenever nuclear substances and radiation devices are present in the room and the room is unoccupied.
