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: ISO/TS 18090‑1 does not define new radiation qualities. Instead, it uses those radiation qualities specified in existing ISO and IEC standards.
Note 2: Under ISO/TS 18090‑1 other specification is not applicable for much shorter pulses; one example is the time-dependent behavior of the air kerma rate. This may not be measurable for technical reasons as no suitable instrument is available, e.g., for pulses produced by a femtosecond Aser.
Who is ISO/TS 18090‑1-Characteristics of reference pulsed radiation for radiation protection for?
ISO/TS 18090‑1 on characteristics of reference pulsed radiation for radiation protection is useful for:
- Radiologists
- Radiotherapists
- Oncologists
- Health and safety departments
Why should you use ISO/TS 18090‑1-Characteristics of reference pulsed radiation for radiation protection?
The specification and determination of the special characteristics required for radiation protection dosemeters to be used in pulsed fields of ionizing radiation have been excluded from all International Standards for personal and environmental dosemeters issued so far. Due to the increased use of pulsed radiation in medicine and industry, such International Standards are currently under development. A prerequisite for such International Standards is the availability of the required reference fields for pulsed radiation.
ISO/TS 18090‑1 provides you with characteristics of reference pulsed radiation for radiation protection, requirements, test methods, constancy of air kerma rate during the pulse plateau time.
The requirements, characteristics and test methods provided by ISO/TS 18090‑1 assist you in calibrating and testing radiation protection dosemeters and dose rate meters to improve the pulse beam quality and ensure protection from radiation hazards.
By adopting ISO/TS 18090‑1 the user can enhance the efficiency and performance of photon radiation detectors.
