If a radiographer's dosimeter goes "off-scale," what is the best course of action?

When a radiographer's dosimeter goes "off-scale," it indicates that the amount of radiation exposure has exceeded the measurable limits of the device. This situation is critical as it suggests potential overexposure to radiation, which can pose serious health risks. Therefore, the best course of action is to cease work and turn in the film badge for proper assessment.

By stopping work, the radiographer ensures immediate safety and prevents further exposure to potentially harmful radiation. Turning in the film badge allows for a professional evaluation of the total exposure that has occurred, which is essential for health monitoring and compliance with safety regulations. This step is crucial for maintaining a safe work environment and managing radiation exposure responsibly.

Other options, such as resetting the dosimeter or resuming work, would disregard the serious implications of high radiation exposure and could lead to additional health risks. Taking a break until another dosimeter is available does not adequately address the potential overexposure either. Immediate cessation of work, along with informing the appropriate safety personnel, is the responsible approach to managing an "off-scale" reading on a dosimeter.
