Radiation is all around us. The sun produces it as do our electronics; but how much radiation can a person of a given age be exposed to until said exposure results in adverse health effects (whether immediate or long-term and experienced some time down the road).
This is a blog post by an IT Worker and Tech Consumer intended to provide general thoughts about possible ways to theoretically improve one’s life, and is not intended to be used as medical advice or nutritional guidelines in any way, shape, or form. Please consult a physician, nutritionist or official government authority such as Health Canada‘s Healthy Food Guide, CMA, AMA or the CDC, along with numerous other sources to get a wider perspective, before making any life-altering decisions.
There are two types of radiation to worry about, namely: ionizing and non-ionizing radiation.
Non-ionizing radiation is a product of natural sources such as cosmic and atmospheric radiation , the largest of which is the sun which cause minimal damage as long as they are taken in limited daily doses (you are likely to burn your skin from ultraviolet light rays so bad that you’ll have to get out of the sun, before you harm yourself from the sun’s natural non-ionizing radiation). Airline pilots, stewardesses and other workers as well as military personnel and other frequent flyers tend to be exposed to elevated levels of cosmic radiation, which after enough accumulation (typically in terms of years), could cause some long-term health problems.
On the other hand, Ionizing radiation rays are the product of unnatural sources such as X-Rays, MRIs, Body Scanners at airports and assorted electronics, cause the most harm to the human body and have effects that reach to the genetic and molecular level.
Almost every electronic product we use today emits some kind of Electro-Magnetic Frequency (EMF), Heat or Electricity output. From cellphones to computers and from Refrigerators to Microwave Ovens. While the average Consumer’s electronics give off very low levels of Ionizing radiation, some are obviously much worse culprits than others. For mobile phones (cellphones) in particular, the Federal Communications Commission (FCC) provides a measure called the Specific Absorption Rate (SAR) which measures values for cell phones (and other wireless devices). SAR is a measure of the rate of RF (RadioFrequency) energy absorption by the body from the source being measured. The following is a table of some of the top selling cellphone brands with both sales figures and SAR exposure rates shown:

Radiation Data courtesy of SAR Shield‘s Radiation Chart and Sales Figures couresy of Wikipedia.
One trend that presents itself as you look through the sales data and compare it to the radiation ratings is that the first generation of a device brand (regardless of line) tends to have higher radiation ratings than predecessors, and as they try to cram more and more features and computing power into subsequent releases of a given line, the SAR continues to spike sharply upwards, then finally as the brand matures they figure out how to better manage the power and radiation emissions and the SAR drops or maintains its level thereafter. So the takeaway is to buy mature product lines first, or, new product lines which received a very good SAR rating that was lower than older handsets (rare but happens). It may be better stay away from early adoption and first sequel releases until the line has been proven on the market for at least 2-3 years (about the typical cellphone contract duration). These days, practical every phone has the same functions anyway, so ask yourself, do you really need a phone with almost as much RAM/ROM as your laptop or desktop computer? Do you need a nuclear reactor (heatwise) in your pocket at all times of the day, just to send a text message, make a call, watch the odd video or comment on your friends’ status updates? Probably not, so go for the safer (and often times cheaper) established models not the latest and greatest.
Using a hands-free headset may help keep the high-powered wireless transceiver and heat-giving battery cells further away from your face, however if you’re switching to bluetooth or other radio transmitter you may just be trading one atmospheric pollution for another. Traditional radio frequencies are better than Bluetooth, which is better than a Wireless hotspot, which is better than using the phone directly next to your head. Any speaker phone or voice command functions built into the phone itself could also go a long way if you can handle the frustration of trying to get it (or the person on the other side) to recognize what you are saying as you repeat yourself over and over (again, perhaps trading one form of bodily stress for mental stress and extra work which surely doesn’t help that much). Either way, carrying (when not in use) and holding (when in use) the phone away from your head and body whenever possible (especially when a call is connecting or large amount of data is being pulled down from the mobile network), and reducing durations of use, especially by children, will be a helpful course of action on the short-term. When it comes to larger devices like tablets, e-readers or laptops, never use those items directly on your bare skin, or on your legs/crotch region (even through clothes the heat they generate can be enough to cause damage to sperm count and/or potential have carcinogenic side-effects in both males and females).
- Distance – Always keep at least 80 cm (31.5 inches or 2’7″) away from your screen for the sake of your eyes, and especially keep this distance away from the vent of your computer or laptop, and keep the area around the vent clear of obstructions such as loose papers and other objects. Computers can quickly overheat when the vent becomes blocked or dusty, so be sure to frequently clean your workstation, desk or other areas you tend to use the computer most.
- Temperature - Work in an environment where you have clean air, great circulation and suitable temperature.
- Air Quality – Reducing airborn particulates by filtering your air is a great way to reduce the amount of toxins your body has to process.
- Plants – Again on the air quality topic, keeping plants nearby can help filter the air in your immediate workspace; but not just that, certain household plants such as Cactus and can actually absorb radiation while they improve air quality in your home.
- Nutrition – Your body has the capacity to fight off or recover from the negative side-effects of radiation exposure. A diet rich in Vitamins A, B, C and D as well as essential minerals and nutrients such as Iron, Potassium and Calcium, will help you ensure good health and the ability to minimize harmful side-effects. The following are good foods for those with higher exposures:
- dates (high in Iron and Vitamin B3)
- bananas (high in Potassium)
- carrots (high in Vitamin A)
- spinach (high in Vitamin A)
- mangos (high in Vitamins A & C)
- wheat and whole grains (high in Vitamins B1 & B6)
- pasta (high in Vitamin B2)
- seeds/nuts (high in Vitamins B3 & B6)
- asparagus (high in Vitamin B3)
- sweet potatoes (high in Vitamins A & B3)
- broccoli (high in Vitamins B3 & B5)
- avocado (high in Vitamin B3 & B5)
- leafy green vegetables (high in Vitamins A, B7, B9 & D)
- lean animal meats including Oyster (high in Vitamin B12)
- oranges (high in Vitamin C)
- apples (high in Vitamin C)
- blueberries (high in Vitamins A & C and antioxidants)
- cherries (high in Vitamin C and antioxidants)
- eggs (high in Vitamins B7, B9, B12 & D)
- mushrooms (high in Vitamin D)
- sunlight and fresh air (great source of Vitamin D, but see note on limiting exposure)
- Upgrade – Not to add to the massive amount of e-waste produced every year, but upgrading your computer to a newer model can significantly reduce your radiation exposure. Even a 5-year old laptop can produce up to 80% more radiation than today’s models, so check your ; and consider e-waste recycling your old computer and electronics if you have a program in your area.
- Disconnect – Researching, designing, testing, developing, hacking, testing some more, reporting to team, virual meetings, webinars, demonstrations, constantly communicating online; these are the minimum things that an IT Worker is expected to do in order to reach that often sought after “superstar” status, but these days its also increasingly common that it be required just to be given a “good employee” status on a performance review. For this reason, its incredibly important to remember to give yourself a break periodically and completely disconnect (for stress reasons as well). No checking one more email, no more tweaking, no more industry news articles or journals, just unplug and relax and do something (a hobby maybe, or activity with your friends/family) unrelated to IT.

BC$ = Behavior, Content, Money
The goal of the BC$ project is to raise awareness and make changes with respect to the three pillars of information freedom - Behavior (pursuit of interests and passions), Content (sharing/exchanging ideas in various formats), Money (fairness and accessibility) - bringing to light the fact that:
1. We regularly hand over our browser histories, search histories and daily online activities to companies that want our money, or, to benefit from our use of their services with lucrative ad deals or sales of personal information.
2. We create and/or consume interesting content on their services, but we aren't adequately rewarded for our creative efforts or loyalty.
3. We pay money to be connected online (and possibly also over mobile), yet we lose both time and money by allowing companies to market to us with unsolicited advertisements, irrelevant product offers and unfairly structured service pricing plans.
