Which of the following is NOT listed as one of the four major occupational hazard stressors?

Radiological Hazards
Explanation:
The main idea is that the four major occupational hazard stressors are chemical, physical, biological, and ergonomic hazards.

To see the others: chemical hazards involve toxic substances; biological hazards involve pathogens; ergonomic hazards relate to design and repetitive motion issues. That’s why radiological hazards are not among the four.
