Part 3/5:
To further illustrate the impact of radiation sources, the speaker conducts a practical demonstration. By moving closer to a radioactive source down the corridor, the readings on the detection device swiftly rise, surpassing 100 counts per minute and eventually stabilizing around 1,100 counts per minute after sufficient time is allowed for measurement.
Comparison of Detector Sensitivity
Throughout the discussion, the speaker also contrasts the detectors used during the 2011 incident. They noted that the high sensitivity detectors utilized then were battery-operated and, as such, had various limitations. Although current readings reflect much lower counts, the differences in technology and sensitivity can inform risk assessments in potential radiation exposure scenarios.
