Are DSi radiotracing techniques dangerous for users?
Not at all ! We work below the exemption threshold. The radioactivity rate is extremely low and don’t even need protection. In order to compare, one year of work with DSi radioactivity techniques = 1200 µSv in comparison of the natural rate that is 1000 µSv. A trip from Paris to New York can lead to 100 µSv and a radiography can lead to 1000 µSV.
