Update on Aug 2, 2021: the September issue of QST has a free article about Understanding the Changes to the FCC RF Exposure Rules.

The FCC has announced that rule changes detailed in a lengthy 2019 Report and Order governing RF exposure standards go into effect on May 3, 2021. The new rules do not change existing RF exposure (RFE) limits but do require that stations in all services, including amateur radio, be evaluated against existing limits, unless they are exempted. For stations already in place, that evaluation must be completed by May 3, 2023. For more information see: www.arrl.org/news/updated-radio-frequency-exposure-rules-become-effective-on-may-3

We have two ways to comply with the rules. One method involves taking measurements with the appropriate instruments. Another method is a predictive model with calculations based on antenna theory and documented properties of the transmitters and antennas at your station.

Below are some of the RF exposure calculations I created for the antennas at my station using a calculator that is available on-line. See below the table for links to sources of the information and the calculator that I used.

I also found a spreadsheet from Ham Radio School, adapted and updated it to create this spreadsheet that seems to be easier to produce calculations.

I used the most conservative estimates possible. For example, I assumed a 100 percent duty cycle on FM and entered the maximum power rating for each band from the tech specs for my radios. I chose not to calculate power losses from feedline. You might want to use a feedline power loss calculator to estimate a more accurate power level at your feed point.
Please let me know if you see any mistakes.
