Radiation...

"

  • For strongly penetrating radiation the depth d=10 mm is used and the personal dose equivalent is denoted as H_p(10).
  • For weakly penetrating radiation the personal dose equivalent in the skin at d=0.07 mm, H_p(0.07), and in the lens of the eye at d=3 mm, H_p(3), are used.
  • H_p(d) can be measured with a dosimeter that is worn at the surface of the body and covered with an appropriate layer of tissue equivalent material.

From Chapter 4.2 Operational Quantities for Radiation Monitoring, Radiation Oncology Physics: A Handbook for Teachers and Students.


And I couldn't stop thinking: "is worn at the surface of the body and covered with an appropriate layer of tissue equivalent material", "is worn at the surface of the body and covered with an appropriate layer of tissue equivalent material", "is worn at the surface of the body and covered with an appropriate layer of tissue equivalent material", "is worn at the surface of the body and covered with an appropriate layer of tissue equivalent material", "is worn at the surface of the body and covered with an appropriate layer of tissue equivalent material", "is worn at the surface of the body and covered with an appropriate layer of tissue equivalent material", "is worn at the surface of the body and covered with an appropriate layer of tissue equivalent material", "is worn at the surface of the body and covered with an appropriate layer of tissue equivalent material"...
