The LD50/60 for humans is approximately _____ Gy.

The LD50/60, or lethal dose for 50% of the population within 60 days, is an important measure when assessing the effects of radiation exposure on humans. For humans, this value is approximately 3.5 Gy. This measurement indicates the threshold dose of radiation that is expected to cause death in 50% of those exposed within a specific timeframe, which is significant for understanding the level of radiation that can lead to acute health consequences.

Doses above this level greatly increase the risk of severe biological damage, and at around 3.5 Gy, the detrimental effects on the hematopoietic system and other critical body systems become pronounced. Knowledge of this value is vital in fields such as radiation safety, medical treatment planning, and emergency preparedness in the event of radiation exposure incidents.

Consequently, understanding the LD50/60 helps in evaluating the potential impact of radiation exposure in various scenarios, including occupational settings and nuclear accidents.
