There are several methods for measurement of x-ray radiation, such as an ionization chamber and a scintillation detector. However, neither of these techniques are particularly simple or "cheap" to implement as a do-it-yourself project. One also has the problem of calibration for such a device; after all, what's the point of building it if the indication has no quantitative benchmark? My best suggestion, if you are really concerned, is to obtain a photographic film badge dosimeter, fasten it to the outside of the device in question, run the device for several hours, and then have the film badge developed and evaluated with a densitometer. There are outside service organizations who will provide such a service, but you will probably not like the cost. The best approach would be to find a friend who works for a hospital radiology or nuclear medicine department and has some "pull" to do a little favor... :-) Larry Lippman @ Recognition Research Corp.
