  1. How much radiation do I receive if I get a CT?

  2. Well it depends what type of CT you receive. For example, one single CT brain perfusion study is about the same equivalent radiation exposure as 200 diagnostic radiographic exams (Williams, 2010). The radiation exposure will always fluctuate depending on the type of exam you would would be having.

  3. There are some wave explanation from Cluster which may be of interest. For this season Cluster was in eclipse for most of BARREL's campaign. dosimeter badges. 2013 is clear and we should be able to provide some unique high latitude wave measurements. So along with all the other spacecraft, dont forget Cluster :)
