Final answer:
Option 1, wearing the personnel monitoring device secured snugly to the wrist, is incorrect as it can lead to inaccurate data due to movement. The device should ideally be attached to a belt or waistband or worn as a necklace for accurate exposure readings.
Step-by-step explanation:
The personnel monitoring device is designed to keep track of exposure to hazardous environments, often related to radiation. It is important that the device is worn correctly to provide accurate data. When describing the correct ways to wear such a device, Option 1: Secured snugly to the wrist is not correct. The device should not be worn on the wrist, as it can be subjected to movement that can lead to inaccurate recordings.
Appropriate ways to wear the device include Option 2: Attached to a belt or waistband, ensuring it remains close to the body's trunk where most critical organs are; Option 3: Worn as a necklace, especially if it is a dosimeter meant to measure exposure to the thyroid or chest area; and Option 4: Placed in a pocket, though this is less ideal as the device can still be exposed to movement or be partially shielded by the body.
