Choosing the right detector is key for accurate dose measurements in water. Which detector characteristics have a major influence on my measurement results? Which trade-offs are acceptable for a specific measurement task? Is a diode automatically the best choice for small field dosimetry? It all depends.

In this educational webinar, Jan Würfel, research scientist and detector expert at PTW Freiburg, will provide answers to frequently asked questions on radiation detectors and give advice on how to choose the best detector for a specific application. He will go into detail about basic detector properties, address factors that need to be taken into consideration when selecting a detector for dose measurements in water, and give examples of suitable detectors.

Key topics covered in this webinar include:

  • Discussion of important detector properties, such as range of use, measurement speed, long-term stability or energy response, and their relevance.
  • Typical examples of dose detectors with the discussed properties.
  • Overview of major detector applications and their specific requirements.
  • Typical examples of detectors suitable for use in reference, relative and small field dosimetry.

We look forward to sharing our knowledge and best practices on detector selection and use with you.
