The World Health Organization (WHO) notes in its Fact Sheet 304:
"To date, the only health effect from RF fields identified in scientific reviews has been related to an increase in body temperature (> 1 C°) from exposure at very high field intensity found only in certain industrial facilities, such as RF heaters. The levels of RF exposure from base stations and wireless networks are so low that the temperature increase is insignificant and does not affect human health."

The FCC has established rules requiring transmitting facilities to comply with RF exposure guidelines. The limits established in the guidelines are designed to protect the public health with a very large margin of safety. These limits have been endorsed by federal health and safety agencies, such as the Environmental Protection Agency (EPA) and the FDA.
The FCC has established exposure guidelines for RF devices operating in the 300 kHz to 100 GHz range. These safety guidelines are outlined in the publication, OET Bulletin 65 Edition 91-01, "Evaluating Compliance with the FCC Guidelines for Human Exposure to Radiofrequency Electromagnetic Field", and can be found at http://www.fcc.gov/encyclopedia/radio-frequency-safety.
The general-population exposure limits set by the FCC for the frequency range utilized by the meters/radios and other devices such as cordless phones and baby monitors is 0.6 milliwatts per centimetre squared (mW/cm2) at 902 MHz.
R900 device transmits for less than one minute total per day and for 7 milliseconds at a time. The exposure to radio frequency energy at a distance of 1 foot from the meter is never more than 0.08 mW/cm2 for the Fixed Network Messages. This is approximately 8 times lower than the exposure limit set by the FCC. Standard Mobile Messages are an order of magnitude lower.

• OSHA: The Occupational Safety and Health Administration's (OSHA) Health Response Team has been involved in studies related to occupational exposure to RF radiation. https://www.osha.gov/SLTC/radiation_nonionizing/index.html.

Personal information such as an address, account number or name is never transmitted through the meter. A serial number is assigned to each property to track the water usage data coming from the meter.

Health Canada's Safety Code 6 outlines and specifies maximum levels of human exposure to RF energy at frequencies between 3 kHz and 300 GHz, to prevent adverse human health effects. Safety Code 6 also specifies maximum allowable RF contact and induced body currents to prevent the physical perception of internal currents resulting from RF energy in uncontrolled environments, and to prevent RF shock or burns to personnel in controlled environments. The code also serves to provide guidance for evaluating RF exposure levels, to ensure that personnel in controlled and uncontrolled environments are not exposed at levels greater than the limits specified in this code.

Yes. Radio endpoints being installed have been tested in accordance with Title 47, Part 15 of the Code of Federal Regulations and have been certified by the FCC.
The R900 is also certified by Industry Canada who has adopted Health Canada's "Safety Code 6: Limits of Human Exposure to Radio Frequency Electromagnetic Fields in the Frequency Range of 3KHz to 300GHz".

R900 wireless communication equipment operates within the Industrial, Scientific, and Medical (ISM) band which includes frequencies from 902 MHz to 928 MHz.

The Food and Drug Administration (FDA) and the FDA's Center for Devices and Radiological Health (CDR) have classified radiation emitted by devices operating at these RF frequencies as "non-ionizing." Other types of non-ionizing radiation devices include televisions, radios, remote controls, and other devices that use visible light and infrared light.

The FCCs document OET Bulletin 65 Edition 97-01, "Evaluating Compliance with FCC Guidelines for Human Exposure to Radiofrequency Electromagnetic Fields", details how to measure or calculate levels of RF radiation and to determine compliance of RF facilities with exposure limits.
Additionally, FCC OET Bulletin 65 Supplement C Edition 01-01 provides further guidance on determining compliance for portable and mobile devices.
These documents may be found at http://www.fcc.gov/encyclopedia/radio-frequency-safety.

The transmitting devices operate in compliance with FCC 47 CFR Part 15 regulations, which require coexistence with other Part 15 certified devices. Within the 902-928 MHz frequency band, operation is limited to frequency-hopping, direct sequence spread-spectrum, and digital modulation intentional radiators. This rule facilitates multiple devices operating in the same location. This includes devices such as security systems, pacemakers, cell phones, and cordless phones. The meter/radio's transmit signal is of very short duration (7 milliseconds), which further decreases the potential for interference with other devices. For comparison, 7 milliseconds equates to approximately one minute total transmission time per day.
