deborahflarson replied to a discussion2 years agoThere is no DOT-recommended service life for steel and aluminum cylinders, but the CGA says they may be employed repeatedly as many times as desired if they pass both hydrostatic and visual examinations every five years. Typically, services in hydrostatic testing are mandated to ensure cylinders that are safe and compliant over time.

ndtcs replied to a discussion2 years agoTo calculate the safe working distance from a radiographic source, you’re correct that the inverse square law is the starting point, as it describes how radiation intensity decreases with the square of the distance from the source. However, there are additional factors to consider, such as the use of collimators and the specifics of the setup.
Collimator and Shielding Effects: A collimator focuses the radiation beam and reduces scatter, meaning the radiation is more directional, which can help limit exposure to areas outside the primary beam. This can allow workers to safely be closer to the source in directions that are outside the collimated beam. However, this reduction will depend on the type and quality of the collimator, so actual dose rates should be measured with a survey meter in the field.
Double-Wall Exposure and Pipe Thickness: With a double-wall exposure and a 1/2" thick pipe, the material itself provides some shielding. However, the attenuation through the pipe won’t be enough to significantly reduce the required safe distance. Again, the inverse square law applies, but you should factor in how the beam is directed based on the exposure technique and orientation of the source relative to other work areas.
Direction of Radiation: Radiation is most intense in the primary direction of the beam, but scatter can occur in all directions. The direction of the radiation (whether it’s horizontal or vertical, for example) will affect where it’s safe to stand. Be especially mindful of any areas where scatter could be more pronounced, such as corners or tight spaces.
Field Survey for Accuracy: The most practical way to determine safe working distances, given the variables of collimation, pipe thickness, and direction, is to perform a radiation survey using a calibrated dose-rate meter. This will give you real-world measurements of the radiation field around the source, taking into account the setup and any shielding effects from the collimator or materials.
For a rough estimate, apply the inverse square law to the expected dose rate at a known distance, but rely on the survey meter to determine actual safe working distances in the specific situation. Always ensure that workers in adjacent areas are adequately shielded or at a safe distance, and post warning signs or barriers to demarcate restricted zones.

luis-lima started the discussion Engine Floormap 3di2 years agoHello friends! I wonder if anyone has the technical references of the 3di floormap engine?
I need one. Silvering no longer sells it, and I need it to replace it on my machine.
I thank everyone for any information!
