The Viking I is the smallest and lightest member of the Viking family at just 6.5 Kg. The Viking I is tailored to a smaller source working culture and in particular for use in areas where evacuation is not always possible or for use next to radiation sensitive devices such as nucleonics detectors on oil rigs. The Viking I is available with a variety of attachments which allow the Viking I to be tailored to your needs and allow you to balance the collimator and attenuation you need with the physical size and weight of the equipment (projector and collimators) that you use. We have a wide variety of collimators available however we can adjust existing components or our unique ability to design and manufacture bespoke components to meet your requirements.
The Viking I houses a collimator that eliminates the hot pass associated with projection radiography. A key feature of the Viking I is that the collimator can be removed and changed by the radiographer on site. This is a key benefit as it allows the projector and collimator to be tailored to the individual pipe or radiograph requirements and allows for the maximum dose restriction to be achieved at the same time. Being able to change the collimator also allows for the aperture of the collimator to be tuned into the work piece and therefore helps to better meet the requirements of IRR 99 to restrict radiation exposure to useful radiation and of course tuning the aperature will help reduce the dose experienced by radiographers and allows for quicker setup times with fewer shielding materials such as GammaShield sheets being required.
The final link of the chain in providing the ultimate flexibility is to cater for those work pieces where it is not possible to use close proximity working equipment. An example of this would be where there is a cluster of small bore pipes where two of three exposures are required on any particular pipe. For this scenaio it may not be possible for the Viking I projector or any projector to be inserted between the pipes and therefore the radiographs could not be conducted. In order to allow radiographs to be taken in circumstances such as these we have developed a projection attachment for the Viking I. This allows for a narrower collimator to be used on a short solid guide tube that may be directly attached to the projector or even for the source to be projected down a conventional guide tube. This again allows for the ultimate flexibility for the radiographer to tailor the equipment to what not only allows for the most efficient way of carrying out the work but also allowing the highest standards of safety to be achieved.
