The robotic rover Curiosity has instruments that detect radiation both inside the spacecraft and in the Mars environment. What is most likely the purpose of this radiation detection?

Radiation can harm astronauts and damage equipment, so measuring it inside the rover and in the Martian environment helps scientists assess the risks of sending people to Mars. This makes “to determine whether human exploration of Mars is possible” the best answer. The measurements are not primarily for developing X-ray technology or searching directly for signs of life, hydrogen, or water.
