Is gamma radiationan an asphyxiative hazard?

Gamma radiation is not classified as an asphyxiative hazard. Asphyxiative hazards typically involve gases or vapors that displace oxygen in the air, leading to suffocation. Gamma radiation, on the other hand, consists of high-energy electromagnetic waves that can penetrate materials and cause ionization, posing health risks primarily through radiation exposure rather than through displacement of oxygen.
