'''Radiation detectors''' provide a signal that is converted to an electric current. The device is designed so that the current provided is proportional to the characteristics of the incident radiation.

Similar to the way that a terrestrial gyrocompass uses a pendulum to sense local gravity and force its gyro into alignment with earth's spin vector, and therefore point north, an ''orbital gyrocompass'' uses a horizon sensor to sense the direction to earth's center, and a gyro to sense rotation about an axis normal to the orbit plane. Thus, the horizon sensor provides pitch and roll measurements, and the gyro provides yaw. See Tait-Bryan angles.

Gadolinium oxysulfide is a promising luminescent host material, because of its high density (7.32 g/cm<sup>3</sup>) and high effective atomic number of Gd. These characteristics lead to a high stopping power for X-ray radiation.
