I have been following with interest the threads here and on APUG about x-ray film, so I decided to jump in. I purchased (2) 100-sheet boxes of 10x12 1/2-speed blue sensitive film, Kodak white box (don't know if that is significant).

Based on the information in the first image, can I assume this film is coated on one side only?
Based on image #2 the safelight recommendation is [ Type M ] and according to the chart shown in the third image that means a #13 filter instead of the GBX-2 usually used for these films? Thanks.
