Which type of radioactive emission has NO mass and NO charge, consisting of high-energy electromagnetic radiation?

📌 Gamma rays are pure electromagnetic radiation (like light, but much higher energy) — no mass, no charge. Alpha particles are helium nuclei (mass 4, charge +2). Beta particles are high-speed electrons (mass ~0, charge −1). Neutrons have mass 1 and no charge but are usually not classified with the three main decay types. Gamma rays often accompany alpha or beta decay as the nucleus releases excess energy.
