How often should external dosimeter readings be reported?

External dosimeter readings should be reported every 15 minutes to ensure timely monitoring of radiation exposure levels. This frequency allows for ongoing assessment of environmental conditions and potential risks to personnel, enabling prompt actions to be taken if exposure levels approach unsafe limits. Regular reporting every 15 minutes strikes a balance between maintaining vigilant oversight and practicality, ensuring that data is collected frequently enough to detect any significant changes in radiation exposure without overwhelming responders with data. This practice is essential in environments where radiation is a factor, as it helps safeguard the health and safety of those involved in rescue operations.
