If you think that you may be exposed to RF energy above safety limits by all means ask your industrial safety people to survey the fields. Measuring RF exposures, particularly in occupational settings such as yours, should be done by a qualified expert with appropriate equipment, it is not a do-it-yourself project. Professional-grade meters of the kind needed to accurately measure exposures to pulsed radar fields such as you describe are generally quite expensive and require considerable expertise to use, although some high-quality personal exposure monitors are available for about $2,000. Hobbyist-grade meters are too unreliable to be useful. To respond to your second question, various instruments are available to measure RF exposures from the radar, ranging from inexpensive hobbyist-grade meters available online, to very expensive survey instruments from companies that specialize in RF safety.

For all practical purposes this radiation does not reach the brain at all. Nearly all RF energy at 15 GHz that is incident on the body is absorbed within about 1 millimeter from the surface of the body, i.e., in skin. Most of the epidemiological evidence that IARC considered involved long-term use of cell phones, which is a very different exposure situation from the one you describe. The International Agency for Research on Cancer (IARC) has classified RF energy as a 'possible' carcinogen, but this indicates that evidence supports some level of suspicion, and is not a statement that such fields actually do cause or promote cancer. Health agencies have some concern that long-term exposures to RF energy is associated with cancer. However, despite some epidemiological studies of radar operators, there is no clear evidence that working near radar is hazardous, as long as exposures are within international safety limits (which are similar to those in the United States) The World Health Organization has a fact sheet on the topic. To answer your first question, radar emits brief but high intensity pulses of RF radiation that is potentially hazardous at excessive exposure levels. Pulse repetition frequency (PRF): 13–20 kHz.Thank you for this helpful service you provide! First, could long-term exposure in close proximity to a powerful radar be detrimental to human health (we are approximately 20 feet below the radar)? And secondly, is there any device I could use to measure the amount of radiofrequency (RF) or electromagnetic frequency (EMF), or other potentially harmful energy penetrating the tower cab and operations level, and what values would be considered harmful? The radar specifications are listed below. While I realize that there is no proven link between this radar and cancer, it has still caused me concern as this is a ground movement radar, not one projecting upward into the sky. Our tower is ~20 years old, and over those years, two of ~80 individuals who have worked here long term have developed brain cancer. It is Japan's largest airport both in its reputation and in its performance, as it sports no less than four runways, handling over 80 million passengers annually (domestic/international), with over 400,000 flight slots.I am an air traffic controller at a tower facility with an Airport Surface Detection Equipment Model 3 ground movement radar mounted on top of the tower cab. The game is set in Haneda Airport (HND/RJTT) in Tokyo, which represents Japan! You can also select time, wind direction, and section you like for your own Original Stage. Even after game over, you can resume from the middle of the game replay.Īdding to the Game Stage of various play levels, the Extra Stage gives you some special conditions to further liven up the play. Yet as the situation keeps changing according to the directions issued and the timing, clearing the stage always requires precise and correct judgment. The operation is quite simple, just select an aircraft and click Instruction buttons. To clear the stages, a player should issue directions as a tower controller for safe and effective flight of aircraft. We focus on the duties of these controllers in our game scenarios. Since its release in 1998, this air traffic control game has established itself as a long seller, strongly supported by numerous users both inside and outside of aviation fandom.įor the safe flight of aircraft, air traffic controllers play a vital role.
