Radio Frequency (RF) energy radiates into space via electromagnetic waves, moving through space at the speed of light. The oscillating currents of RF waves are able to carry information on signals received by cell phones, Bluetooth, WiFi, and all devices of connectivity. Closely related to microwaves, RF waves are thermal, as well, and share the ability to heat biological tissue.
RF emissions can be attenuated, or dampened, when impacting a barrier of fine metallic mesh. The concept behind the attenuation of electromagnetic waves, by shielding with Metallic fabric, is attributed to Michael Faraday, an Eighteenth Century British Scientist.
The RF shielding material used in NixRay bags and cases are positioned in multiple layers, to achieve optimal dampening, and are positioned to act as an effective barrier between your body and your device.
When RF current is attenuated, or dampened, by NixRay’s multiple layers of Faraday material, this reduction is measured in decibels, or dBs. This reduction scale is logarithmic. For instance, if a shielding fabric has an RF current attenuation rating of -3 dB, it will block 50% of RF energy. A fabric with a rating of -6 dB will block 50% of 50%, allowing only 25% of RF penetration.
NixRay’s antimicrobial shielding materials have ratings of -60 dB and -95 dB, which means that they will only permit 0.000.001 and 0.000.000.001 or one ten-millionth and one ten-billionth of the original signal power to pass, respectively. Our products employ the same MIL-SPEC shielding fabric currently used by the U.S. military, and NASA.
RF currents are subtler than lower frequency waves, in that contact with them does not cause muscle contraction and pain. Rather, they skim surfaces in a shallower manner, known as Skin Effect.
RF wave patterns so rapidly change direction, that they don’t cause nerve tissue to depolarize, triggering pain sensors. However, RF frequencies have similar frequency and thermal effect as microwaves used in microwave oven technology and have the ability to rapidly heat biological tissue, and elevate internal body temperature, without stimulating the nerves to sense pain. This property makes infants, children, and fetuses in utero, whose tissues are more delicate, most vulnerable to RF damage, as well as more delicate parts of adult anatomy, such as eyes, ears, and glandular structures near the ears, and testes.
Because RF waves are non-polarizing, unlike common AC current, they are non-ionizing. In the past, researchers held the belief that RF frequencies could not stimulate tumor or cancer growth, or other tissue damage, because RF doesn’t produce free radical ions.
But current research shows a large and growing body of empirical and peer reviewed evidence that the thermal effect of RF can negatively target human tissue via a different pathway. It interferes with the body’s ability to heal cellular damage. A strong connection is emerging showing a relationship between heavy proximity of RF devices and specific cancers of the testes, as well as tumors, both benign and malignant, of the parotid gland, a part of the salivary system located near the ear.
And there is a very large body of research, from all over the globe, cautioning parents and schools to be aware of potential damage to the much more delicate cranial structures of toddlers and children, whose ear, eye, and cranial tissue are not as guarded by greater adult depth and bone thickness, making them exposed to RF frequency’s shallow Skin Effect.
Since RFID tags can be attached to cash, clothing, and possessions, or implanted in animals and people, the possibility of reading personally-linked information without consent has raised serious privacy concerns. When RFID devices (eg: credit cards, passports, etc) are surrounded by the fabrics in certain Nixray products, they will not be detectable or read by RFID readers. Nixray products that offer this protection are the Hipster/Holster and the soon to be released NixRay Cage.
All NixRay products are lined with the same RF shielding and antimicrobial fabric currently used by the U.S. Government and NASA. We source our shielding fabrics from the same manufacturers and they are all MIL-SPEC, meaning that they have undergone stringent testing and achieve consistent ratings. Our products protect you using barrier fabrics of 60 dB and 95 dB ratings, the silver component of its metallic mesh also providing you with lab proven antimicrobial protection.
Products & Care
All NixRay products are manufactured in the USA. Our production plant is in the heart of what used to be the center of American Fabric manufacturing in Fall River Massachusetts and is owned and operated by women.
We do not use any leather in our NixRay products. Our primary fabric is durable waxed canvas and RF shielding. In addition we use reflector fabric, seatbelt fabric, custom double coated hardware and Italian copper zippers.
If you get a stain on your case, simply cover with corn starch, wait overnight and then rub it off with a damp sponge. Waxed cotton will patina naturally with age.
You can also buy a small waxing kit to reapply wax.
All NixRay products are constructed of durable, wearable natural fibers, treated with triple filtered beeswax. Waxed cotton is highly water resistant, but not fully waterproof, nor immersible. So in a heavy downpour, slip your NixRay phone case into a handbag or pocket.
NixRay products are water resistant. You can purchase a small waxing kit to reapply wax.
The NixRay products are water resistant. However, in a heavy rain, wear it under your raincoat (hipster) or store your cell phone in a bag (cell phone pouch).
Waxed cotton patinas with age. It will get more “lived in”. Washing it is not advised as you will ruin the waxed finish. Let it age.
If you spill something onto your NixRay, wipe it gently with a clean cloth moistened with clear water. Never use soap on your NixRay, as soap will strip your NixRay’s waxed water repellent finish.
To remove oily stains, gently wipe with clear water, and apply a paste of water and cornstarch to the spot. Cover with a clean cloth, weigh down with something heavy, such as a book, and leave overnight. Remove the towel and the weight, allow cornstarch to dry, and it will dust off easily, taking the oil stain with it.
