Neutron monitors

  1. Calibration of neutron monitors for Am/Be neutrons in terms of ambient dose equivalent H*(10).
  2. Calibration performed using shadow cone technique
  3. Ambient dose equivalent rates of approximately 20 - 150 μSv/h

Other services

Other services such as in situ calibration of source output for protection-level sources and personal dosemeter irradiations. Details of the available services are listed on the NATA website.
