A Geiger counter.
Radiation is an emission. For example, gamma radiation from a nuclear decay is an emission of energy, photons.
A geiger counter measures radioactivity. It detects the emission of nuclear radiation from alpha particles, beta particles, and gamma rays.
X-rays are not a type of nuclear radiation. They are a type of electromagnetic radiation.
neutron emission
Radiation generally describes non harmful waves such as radio waves and light wave while nuclear radiation usually describes emission of harmful gamma rays.
Both have 2 protons and 2 neutrons
There are only three types of nuclear radiation - Alpha, Beta & Gamma.
A Geiger counter, also called a Geiger-Müller counter, is a type of particle detector that measures ionizing radiation. They detect the emission of nuclear radiation: alpha particles, beta particles or gamma rays. A Geiger counter detects radiation by ionization produced in a low-pressure gas in a Geiger-Müller tube

A Geiger counter, also called a Geiger-Müller counter, is a type of particle detector that measures ionizing radiation. They are notable for being used to detect if objects emit nuclear radiation.
Neither, a CAT scan is one where computers are used to synthesise an image, but the radiation used is usually X-rays, though positron emission can be used, in this case it will be using appropriate radiation sources. Fusion and fission don't come into it.
Spontaneous emission of ionizing radiation as a consequence of a nuclear reaction, or directly from the breakdown of an unstable nucleus; The radiation so emitted; including gamma rays, alpha particles, neutrons, electrons, positrons, etc
