Which of the following is NOT a requirement for entry into a High Radiation Area?

In a High Radiation Area, several requirements are established to ensure the safety of personnel who may be exposed to radiation. One of the essential requirements is that individuals must receive proper training, which includes Radiological Worker I training. This ensures that workers understand the risks associated with radiation exposure and know how to operate safely within such environments.

A supplemental dosimeter is necessary to monitor radiation exposure more accurately in areas where radiation levels can fluctuate. This additional device complements a primary dosimeter, enhancing a worker's ability to track their exposure over time.

A personnel dosimeter is another key requirement as it is used to measure the amount of radiation that a worker is exposed to during their time in the area. This device is crucial for maintaining safety standards and for ensuring that exposure limits are not exceeded.

Personal protective equipment (PPE), while important in various work environments, is not specifically a requirement for entry into a High Radiation Area. While PPE can provide additional safety against contamination or other hazards, the primary requirements focus on training and radiation monitoring devices rather than generalized protective gear. Consequently, the correct response indicates that PPE is the item that does not fit the specific entry requirements for High Radiation Areas.
