Well, what's the point of this blog? OK, let's be clear. This is not a stage for my drama, but rather a record of my daily work in GafChromic EBT film. As the data, both what I collect myself, and what I digitize from the literature, grows, there need to be a way to organize them. For now, I believe that a blog would be a good way for me to practise my writing skills, and provide a searchable record of data that I have collected.
On Januar 06, 2009, I returned to work after 3 week holiday break to visit my family in Vancouver. First order of business is reading the temperature log of TinyTag, which is part of our study on the effect of humidity on sensitivity of film. Three weeks of winter did gave us many days of relatively dry environment, but the humidity never went below 5%. Not having a background in diffusion physics, I can not comment on how our environemnt compares with Rink etc's drying oven, which is essentially zero humidity at 50 degree celsius over 24 hours, compared to our 5% humidity over several days. The graphs showed that humidity recovered during the day, due to relatively warm temperature outside. The next step would be to parse these films to extract the length of time spent in sub-7% environment. Again, this criteria is very arbitrary, as I do not know how the speed of water loss scales with environmental humidity.
