Notes

Here are a few Radio Frequency Safety Clothing Options
Radio frequency protective clothing is necessary to protect yourself from the harmful effects of RF radiation. There are a variety of choices to shield your body from this hazard. One such option is the Swiss Shield fabric. This fabric is an amalgamation of cotton thread as well as silver-copper thread. It's light, breathable and simple to wash and sew. In addition it maintains its shielding from EMFs even after 30 washes. It has also been found to be 99% effective in protecting against RF radiation of up 1000 MHz. It's currently priced at around $20 for a linear foot.

Absorption specific rate (SAR)
The SAR of RF protective clothing is a measurement of how well a particular piece of clothing will absorb electromagnetic radiation. It is expressed as Specific Absorption Ratio (SAR) as well as built on ANSI standards. The actual amount of reduction in SAR will depend on the field exposure of the wearer and the specific characteristics of the protective clothing. Therefore, the user should evaluate the performance of the radio frequency protective clothing prior to purchasing.

In the human and rat model, the SAR can be measured as the average SAR over a 10 g tissue volume. Therefore, the averaging time is six minutes for frequencies lower than three GHz and ten GHz for frequencies below three GHz and ten GHz. The reason behind making use of such a long-term mean is not entirely clear. The original standard suggested an interval of 0.1 hour. But, it is not an adequate measurement because of its fact that it suggests poorer precision.

Effect from washing SAR
Chemical compatibility is generally assessed using a test referred to as the permeation breakthrough period. This test measures the amount of chemical permeation through a particular material and is based on chemical content, thickness and the temperature as well as pressure and humidity. The test is typically performed on a sample of a substance with a concentration of 100%, over an extended period of exposure. If the time for breakthrough is more than an hour, the substance is considered to be acceptable. However, the effects of temperature could significantly reduce the barrier properties in protective clothes.

The outcomes of the assessment should be communicated to end users and top management, as necessary. The results should be used in SOPs for protective clothing and equipment and applications that must take into account the factors mentioned in this section. In particular the SOPs and application must include decision trees that connect chemical dangers and levels of protection.

Biochemical effects of RF radiation
There are still a few unanswered concerns regarding the biological effects of radio frequency radiation (RFR). Scientists have carried out epidemiological studies of EMF exposures and health hazards. However, most research has concluded no adverse health effects can be attributed to RF exposure. More research is required to understand the biological consequences of RFR.


RFR can create emf protectors in living cells, and change the electrical properties and dielectric characteristics of molecules. The thermal response may alter the biochemical pathways of living organisms. According to studies, an absorption rate that is greater than 4 W/kg can increase cell temperatures by approximately one degree Celsius. However this effect is dependent on time.

Some studies have revealed that RF radiation can lead to an increased risk of cancer. Two studies, which were conducted by researchers from the National Toxicology Program (NTP) and Ramazzini Institute (ICNIRP), have demonstrated that lab rats and mice exposed to high levels of RF energy can increase the risk of developing cancer.
