Late July 2011, WikiSensor tested the bêta version of its WikiSensor dosimeter in a laboratory of external dosimetry.

the number of pixels
"burnt" (hit) by the radioactive waves.
- Source used: Cobalt
- Dose rate: 50 microsieverts per hour
- Integration time: 1 second
After these experiments, we have concluded that:
- WikiSensor dosimeter is certainly sensitive with a threshold of 5 microsieverts per hour and probably sensitive between 1 and 5 microsieverts per hour.
- The ideal measurement integration time is about 30 seconds. WikiSensor dosimeter is pre-set for a 30 seconds integration time. Users can choose themselves this data integration time (by extending it to be sensitive below 5 microsieverts per hour).
