'''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.

(contracted; show full)ay 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 oxysulfides==

Gadolinium oxysulfide ({{chem|Gd|2|O|2|S}}: Pr, Ce, F powder complex) based ceramics exhibit final densities of 99.7% to 99.99% of the theoretical density (7.32&nbsp;g/cm<sup>3</sup>) and an average grain size ranging from 5 micrometers to 50 micrometers in dependence with the fabrication procedure.<ref>Rossner, W., M.
