RADHAZ to Personnel (HERP)

RF Radiation Hazards for Personnel

Radio Frequency radiation can be harmful if exposure exceeds specified safe limits. With increasing concern among researchers, regulatory bodies and the public about exposure to RF radiation, ensuring that RF exposure safety assessments are accurate and comprehensive is more important than ever.

Phasor Innovation are world leaders in the assessment of RF safety in complex near-field exposure conditions using the latest in Computational Electromagnetics techniques, backed up by sound measurement practices.
Our techniques have been extensively validated by independent measurement.

At Phasor, we conduct assessments in accordance with Australian & international standards. Phasor Innovation is represented on the International Committee on Electromagnetic Safety (ICES).

RADHAZ Assessments

Phasor Innovation can conduct RF Radiation Hazard (RADHAZ) Assessments for personnel in accordance with Australian & International standards, including ARPANSA RPS 3, C95.1 and AS2772.2. Dependent upon the scenario, the RADHAZ assessment may be completed by desktop computation, simulation, measurement and analysis, or a combination of these methods.

The Phasor team are experienced RF Radiation Hazards assessors, and are certified Radio Frequency Radiation Safety Officers (RFRSO) for the Australian Defence Force. Please contact us if you require further information.

Complex Platforms

Phasor Innovation are world leaders in the assessment of RF safety in complex near-field exposure situations, such as in and around:

  • Vehicles
  • Aircraft
  • Ships
  • Fixed Site installations

High-fidelity modelling, combined with targeted measurements where required, provides the most comprehensive and accurate assessment of RF safety where near-field exposure is unavoidable. Traditional measurement-only approaches frequently fail to identify hazards caused by resonances and re-radiation and often result in overly restrictive control measures being implemented.


Near-Body Transmitters

Exposure to RF radiation from devices located close to the body requires careful assessment to ensure that localised hot-spots are below the mandated limits that apply to different parts of the body. Applications that require this type of assessment include:

  • Body-worn and back-pack military radios
  • Hand-held radios
  • Counter-IED and EW equipment
  • Cellular phones
  • Wireless devices
  • Bio-medical devices

SAR Assessments

Specific Absorption Rate (SAR) is a measure of the RF energy absorbed by the human body, and is used to assess safety whenever there is potential for people to be exposed to complex electromagnetic fields that may exceed allowed limits. See for more information.Using the world’s most advanced software and detailed human models, Phasor Innovation can assess SAR with unprecedented accuracy. What’s more, we can apply SAR techniques to virtually any RADHAZ exposure scenario. In addition to exposure from body-worn or hand-held devices, Phasor can conduct SAR assessments of in-situ personnel exposed to complex near-field hazards, such as in vehicles, aircraft, ships and confined spaces. Assessment by SAR in these situations can ensure that personnel are safe, standards are complied with and unnecessarily restrictive control measures are avoided. Computational SAR is now the benchmark for near-field RADHAZ compliance assessment and Phasor Innovation are the experts.
