Full title and description

Radiological protection — X and gamma reference radiation for calibrating dosemeters and doserate meters and for determining their response as a function of photon energy — Part 3: Calibration of area and personal dosemeters and the measurement of their response as a function of energy and angle of incidence. This part specifies additional procedures and data for the calibration of individual and area dosemeters and for measuring their energy‑ and angle‑dependent responses.

Abstract

ISO 4037-3:2019 gives procedures for calibration of whole‑body, extremity and area (portable and installed) dosemeters in photon reference radiation fields (mean energies approximately 8 keV to 9 MeV), describes recommended phantoms and conversion coefficients for matched reference fields, and addresses measurement of response as a function of photon energy and angle of incidence. It notes requirements such as charged‑particle equilibrium and applicability for air kerma rates above 1 µGy/h.

Scope

Specifies additional calibration procedures and data for dosemeters and doserate meters used in radiation protection for individual and area monitoring. Applies to photon reference radiation fields defined in ISO 4037‑1 and is intended for calibrations and type‑testing to determine energy and angular response; it is applicable for air kerma rates above 1 µGy/h and does not cover in‑situ calibration of permanently installed area dosemeters.

Key topics and requirements

• Calibration procedures for whole‑body and extremity personal dosemeters and for portable and installed area dosemeters.
• Use of photon reference radiation fields with mean energies from about 8 keV to 9 MeV (as specified in ISO 4037‑1).
• Measurement of dosemeter response as a function of photon energy and angle of incidence; recommendations for phantoms and mounting.
• Application of conversion coefficients for matched reference fields and guidance when fields are characterized rather than matched.
• Requirement for charged‑particle equilibrium in reference fields and notes on energies/depths where equilibrium may not be inherent (reference depths 0.07 mm, 3 mm, 10 mm).
• Minimum applicable air kerma rate: > 1 µGy/h; exclusion of pulsed reference fields and in‑situ fixed‑installation calibration.

Typical use and users

Used by national and accredited calibration laboratories, instrument manufacturers (dosemeter and doserate‑meter producers), radiation protection service providers, hospitals and medical physics departments, industrial radiography and nuclear facility personnel, and regulatory bodies for type testing, calibration certificates and establishing traceability. Guidance and procedures are followed when issuing calibration certificates and when evaluating dosemeter performance versus energy and angle.

Related standards

These are normally used together when planning and performing calibrations.

FAQ

Q: What is this standard?

A: ISO 4037‑3:2019 is Part 3 of the ISO 4037 series giving procedures and data for calibrating area and personal photon dosemeters and for measuring their response as a function of photon energy and angle.

Q: What does it cover?

A: It covers calibration procedures, recommended phantoms, application of conversion coefficients for matched reference fields, measurement of energy‑ and angle‑dependent responses, and notes on charged‑particle equilibrium and applicable air kerma rates (above 1 µGy/h). It does not cover in‑situ calibration of permanently installed area dosemeters.

Q: Who typically uses it?

A: Accredited calibration laboratories, manufacturers of dosemeters and doserate meters, medical physics and radiation protection professionals, industrial and nuclear facility metrology groups, and regulatory or conformity assessment bodies.

Q: Is it current or superseded?

A: Current — ISO 4037‑3:2019 (Edition 2) replaced the earlier ISO 4037‑3:1999 edition and is the valid international edition published in January 2019. National adoptions or translations may include additional national forewords which can change page counts.

Q: Is it part of a series?

A: Yes — it is Part 3 of the ISO 4037 series. Use together with ISO 4037‑1:2019 (radiation characteristics and production methods) and ISO 4037‑2:2019 (dosimetry procedures); ISO 29661 provides overarching definitions and fundamental concepts for reference radiation fields.

Q: What are the key keywords?

A: Reference radiation, dosemeter calibration, X and gamma radiation, energy response, angular response, air kerma, calibration laboratory, radiological protection.
