Question 10

An astrophysicist uses a portable radiation detector to measure the ambient cosmic ray background in a high-altitude observatory.

The background radiation count rate is recorded as $second0.64\text{ counts per second}$ .

A cosmic-ray muon calibration source is then positioned directly beneath the detector's sensor.

The new reading on the detector's display is $second14.11\text{ counts per second}$ .

Calculate the corrected count rate, in counts per second, detected from the muon calibration source alone.
