A radiation level reaching 60 mrem/hr is classified as which of the following?

A radiation level of 60 mrem/hr is classified as a radiation area. Radiation areas are defined as locations where the dose rate is greater than 0.1 rem per hour (or 100 mrem/hr). This classification is important for ensuring the safety of individuals who may be present in areas with varying levels of radiation exposure.

For context, a high radiation area is defined as an area where the radiation dose rate exceeds 1 rem per hour (or 1000 mrem/hr), and a very high radiation area is an even stricter classification where the dose rate exceeds 5 rem per hour (or 5000 mrem/hr). Therefore, 60 mrem/hr does not meet the criteria for either of these higher classifications.

The term "dangerous radiation area" is not a standard term used in regulatory guidelines pertaining to radiation safety, making it an inappropriate choice in this context. In summary, the classification of a radiation level at 60 mrem/hr as a radiation area is based on established regulatory limits for occupational radiation exposure and safety protocols.
