Answer
Electromagnetic
Explanation
The question is a fill-in-the-blank type, requiring the identification of the type of radiation that includes ultraviolet, beta particles, and gamma rays. These are all types of electromagnetic radiation. Ultraviolet radiation is a type of electromagnetic radiation that comes from the sun and can have harmful effects on living organisms. Beta particles are high-energy, high-speed electrons or positrons that are emitted by certain types of radioactive nuclei such as potassium-40. Gamma rays are a form of electromagnetic radiation, they are produced by the hottest and most energetic objects in the universe, such as neutron stars and pulsars, supernova explosions, and regions around black holes. Therefore, the missing word in the sentence should be "electromagnetic".
