ITU-T K.61 (10/2025)

Guidance on measurement and numerical prediction of electromagnetic fields for compliance with human exposure limits for telecommunication installations

Recommendation ITU-T K.61 helps telecommunication operators to verify compliance with radio frequency electromagnetic field exposure standards promulgated by local or national authorities. This Recommendation provides guidance on measurement methods that can be used to achieve a compliance assessment. It also provides guidance on selecting numerical methods suitable for exposure prediction in various situations.
