How cell phone radiation exposure affects the blood

"Nine out of ten subjects showed observable blood changes due to cell phone radiation exposure."
Blood is the essence of life. It is useful to examine the blood under a microscope to look for any changes in reaction to a stressor. In this exploratory study, ten human subjects were exposed to a cell phone radiation stressor. Their blood was examined under a dark-field microscope to look for changes, if any, from the cell phone microwave frequency. We also investigated whether there might be a protective effect on the blood from consuming the recommended Weston A. Price Foundation (WAPF) diet.

The world has rapidly changed over the past few decades with the advent of cell phones. Almost seven billion cell phones are now used worldwide, of which over five billion are in developing countries. As of January 2014, 90 percent of American adults possessed cell phones, and 58 percent of the users had smart phones.1 Due to increasing affordability along with the many useful functions that cell phones provide, the explosion in cell phone usage is not surprising. Indeed, they have become the leading technology in the brave new wireless world of communications.

THE SAFETY CONTROVERSY

Are cell phones completely safe? There is no consensus on how to address this question with its various complex, multifaceted issues. There are many factors to consider, such as the duration of exposure, a person's age, whether the radiation dose is cumulative or not, the long-term use over a person's lifetime, pregnancy, and how cell phones are being used - and stored - on the body.

Cell phones and smart phones are powered by microwaves, part of the electromagnetic spectrum, which range from 300 to 3,000 megahertz (MHz). The key frequencies used in cell phone communications worldwide are 850, 900, 1,800, and 1,900 MHz (1.9 gigaHz). (A microwave oven, which heats water and the water in food, works on 2450 MHz.)

Cell phones and smart phones both receive and emit these frequencies, smart phones emitting far more than the old clam-shell type of cell phone. The radiation they receive comes from cell phone towers, which is ambient, meaning that it is everywhere, and we are all receiving it, all the time. The radiation coming out of the smart phone is of much higher intensity than that coming from cell phone towers, unless one happens to be located very close to a tower.

There are guidelines in the U.S. for short term exposure to cell phone frequency microwaves, defined in terms of the Specific Absorption Rate (SAR), the rate at which energy is absorbed by the human body when exposed to radio frequency radiation. Specifically, the Federal Communications Commission (FCC) in the United States requires that phones sold have a SAR level at or below 1.6 watts per kilogram (W/kg) taken over the volume containing a mass of one gram of tissue that is absorbing the most signal.2 This is a guideline, not a standard, and is solely based on heat generation by cell phone microwaves, because microwaves are well known to produce tissue heating. However, besides heating, there are other types of biological effects from the extremely low-level microwaves associated with cell phones, called "nonthermal" effects. The Russians have conducted many studies on the nonthermal effects, which they consider more significant than thermal effects, and as a result, they adopted a more stringent guideline that is sixty to one hundred times lower than U.S. guidelines.
