Many groups use specific vacuum tools [i.e inlet, and outlet gas arrangements] within which the sample is stored and placed in gamma chamber.
If instead of that, a vacuum sealed glass conatiner containing the sample is placed withn gamma chamber, can it withstand it or will collapse?
You can probably not do this kind of experiment with any kind of glass. The glass will withstand, but will absorb. The absorbance depends on the dosis, on the composition of the glass, and on the wavelength. Probably also on the ageing of the glass submitted to such treatement. Therefore, even if the glass resists, whatever it is, you'll probably never know the exact dosis received by the sample, and this is the major problem. More details in the link below and in the attached paper.
Moreover, because of the defects induced by gamma rays in the structure of the glass, a leak is not to be excluded if the beam is localised.

i think better you do some chemical dosimetry. you place fricke dosimetry solution inside vacuum sealed glass (in vial), measure the optical density and absorbed dose. you will get some idea on loss of dose due to glass. Apply this correction while using polymer sample.
In gamma radiation you can irradiated almost everything(poder film solutions, etc.) in vacuum, in a sealed glass ampoule. The gamma rays goes trough the glass until the simple with almost the same radiation absorption. It could be calculated by Fricke dosimetry, but it is not necessary. the absorbed dose will be more tan 98 or 99%.
you can check on few of my papers or from D. Carlsson. We exposed PE or PP films sealed in pyrex tube under vacuum and placed in liquid nitrogen to observe radiclals R° and then following the fixation of oxygen to get RO°. The same experiment in sealed ESR tube allowed to detect and titrate radicals by ESR. However it was necessary to anneal the bottom of the tubes with a torch to remove the brown color produced in pyrex by gamma rays (dose rate 1MRad/hr)
