A laboratory uses two lamps to inspect a coating. Lamp A emits infrared radiation and lamp B emits ultraviolet radiation. A technician is exposed to radiation from either lamp for the same time and at the same intensity.
Explain why the hazards to the technician are different for the two lamps, and suggest one way the technician could reduce the dose from lamp B.
