We don't have a weight restriction, but we do have the following cautions regarding material thickness in our procedure:
Failure to follow these guides could result in the release of radioactive material to the General Public. The following limits for wall thickness are to be followed when using SAM for free release. Plastic and Paper.............less than 3" Aluminum.....................less than 1.5" Iron............................less than ΒΌ" Any items with thicknesses greater than previously mentioned limits must be opened or taken apart to reduce all areas to less than these limits. For example; Notebooks, books, procedures, SHALL be opened, valves may be dismantled, gauges may be taken apart to reduce their total thickness. Any items with thicknesses greater than these limits CANNOT be released using this system as their wall thickness and material composition will attenuate gamma rays emitted from internal contamination.

The manual does not provide a value, except 60 Kg when using scale. Anybody out there define/describe or have a weight limit?
