What is ISO/TS 18090‑1- Characteristics of reference pulsed radiation for radiation protection about?
ISO/TS 18090‑1 discusses the characteristics of reference pulsed radiation for radiological protection. ISO/TS 18090‑1 is an international standard on photo radiation to ensure radiological protection. ISO/TS 18090‑1 is the first part of a multi-part series that specifies the characteristics of reference pulsed radiation for calibrating and testing radiation protection dosemeters and dose rate meters concerning the response to pulsed radiation. The radiation characteristics include the following:
Time-dependent behavior of the air kerma rate of the pulse Time-dependent behavior of the X-ray tube high voltage during the pulse Uniformity of the air kerma rate within a cross-sectional area of the radiation beam Air kerma of one radiation pulse Air kerma rate of the radiation pulse Repetition frequency
ISO/TS 18090‑1 directly applies to pulsed X-radiation with pulse duration of 0,1 mills up to 10 s. This covers the whole range used in medical diagnostics at the time of publication. Some specifications may also be applicable for much shorter pulses; one example is the air kerma of one pulse. Note 1:
