In order for researchers at SLAC to develop their globally-recognized work on particle accelerators and such, they must adhere to the regulations outlined in the Occupational Radiation Protection Program (10 CFR 835) by the U.S. Department of Energy’s Office of Environment, Health, Safety, & Security. One of these requirements is to monitor areas that are or may be exposed to radiation. To do so, SLAC’s Radiation Protection Department is tasked with managing dosimeters (pictured below) at over 700 locations across the SLAC campus. Managing area dosimeters at SLAC is no simple feat. Because of the difficulty of locating a single dosimeter within a 426 acre industrial and laboratory facility, the biannual cycle of exchanging dosimeters is colloquially referred to as an “easter egg hunt.” Recurring issues in the original and current system are that the operation is slow, inefficient, prone to human error, and difficult to manage. With the problems listed above in mind, Ryan Ford had a vision to create a user-friendly iOS application that would greatly improve the efficiency of the operation and make it easier to manage 700 locations. This new app, called “Dosi Xchange”, was written in Swift 4.0 using Xcode, an integrated development environment developed by Apple.
