EMF Safety Assessment



EMF Safety Assessment - microcells

Micro cells operate at low power and typically have small compliance zones



Example EMF Safety Assessment


Yellow – Public limit

Red – Occupational limit

EMF Assessment Methods

Calculations or Measurements?

EMF Assessment method depends on site & environment

Calculations - suitable in many cases, & have significant benefits - accurate, fast & cost effective.

Measurements - required in very complex environments.

Field Monitoring- Field monitoring is effective when working on towers for safety - Field surveys can provide public reassurance- Continuous monitoring – limited long term benefit where EMF

levels are low and stable

ITU Recommendations - guidance on both calculation and measurements

ITU Recommendationsfor EMF Assessments


ITU-T K.91 guidance on how to assess and monitor human exposure to radio frequency (RF) electromagnetic fields (EMF) in areas with surrounding radio communication installations based on existing exposure and compliance standards – inc advantages and disadvantages of methods

ITU-T K.83 guidance on how to make long-term measurements & monitoring of EMF in the selected areas that are under public concern, in order to show that EMFs are under control and under the limits.

ITU-T K.70 defines techniques which may be used by telecommunication operators to evaluate the cumulative (total) exposure ratio in the vicinity of transmitting antennas and to identify the main source of radiation – includes EMF Estimator software

ITU-T K.52 Guidance on complying with limits for human exposure to electromagnetic fields (telecommunications installations and handsets)

ITU-T K.61 Guidance to measurement and numerical prediction of electromagnetic fields for compliance with human exposure limits for telecommunication installations


EMF Assessment Example - Australia

Environmental EMF report is prepared for all base stations - follows Government calculation method & gives communities EMF information.

Site ICNIRP Compliance Assessment is prepared for all base stations - follows accredited calculation and measurement process

Government conducts site compliance audits & measurements at selected sites – ensures compliance, accurate information & public trust

All site reports on internet database www.rfnsa.com.au

Public confidence has increased through transparency
