What Are the Harmful Effects of Security Scanners?
Radiation is a known carcinogen, and any exposure from security scanners is potentially harmful. High levels of radiation are emitted by back-scatter Xray scanners. Millimeter-wave scanners emit low-energy waves. Estimates of any additional risk are speculative, but there is a safety standard that limits the exposure to an individual to 250 uSv per screening and 25,000 urem per year.
Radiation can cause cancer
Many people are concerned about the safety of airport X-ray scanners, and there is some scientific evidence that radiation from security scanners is a carcinogen. These risks are very low and TSA agents do not have to scan passengers. Experts have raised concerns about the effectiveness of airport security scanners and aren’t sure how much radiation is safe for travelers.
Some scientists, however, claim that the danger of radiation is exaggerated. Low doses can actually be beneficial for your body’s ability to repair itself, so radiation may not be as dangerous as people think. This idea was confirmed in a report published by the National Academy of Sciences, which reviewed the scientific research on the effects of low levels of ionizing radiation. It concluded that low radiation levels are associated with cancer in a linear fashion, but that there is no radiation that is completely safe.
Back-scatter X-ray scanners are harmful
ProPublica recently examined whether “backscatter-X-ray scanners” can cause harm to travelers’ health. These machines can x-ray passengers as they pass through airport security checks. Six to 100 passengers on American airlines have been diagnosed with cancer by the ionizing radiation they emit. Transportation Safety Administration responded that backscatter Xray machines are minimally harmful and that millimeter waves offer greater safety than xrays.
A backscatter X-ray scanner is a powerful machine that aims to produce high-quality images. This type of X-ray uses a special technique called the helium-argon-arc technology. The radiation emitted by the device is as high as ten megawatts per scan. This radiation is equivalent in time to flying an hour in the United States. It would take about 200 backscatter X-ray scans to reach this amount.
Millimeter wave scanners emit low energy waves
Millimeter wave scanners emit radio frequencies in the millimeter range, which is part of the electromagnetic spectrum. They emit low energy waves through two antennae that rotate around the body of the scanner. These low energy waves are relatively harmless, and they have several applications. The TSA has installed hundreds of these devices at airports around the U.S., and other countries are also using these technologies for security purposes.
The World Health Organization’s electromagnetic field research hasn’t concluded that the millimeter wave scanners can be safe, but some researchers believe that they could have a beneficial biological effect. This is because these scanners interact with large molecules, small cells, and the entire body. In addition, the scanners are not as invasive as x-rays, and are therefore safe for most people. There are concerns that millimeter-wave scanners could cause injury to the human body. It is important that consumers are aware of the risks and make informed decisions before undergoing the procedure.
Uncertainty exists about the extent of any additional risk.
Although the amount of ionising radiation released by security scanners is quite low, there are several risks associated with it. High-dose ionising radiation may lead to genetic damage in cells. It can cause cloudy lenses and increase the risk of cardiovascular disease. Low-dose ionising radiation does not appear to increase cancer risk. Security scanner radiation has a very low risk of being exposed for short periods.
The assets’ motivation, capacity, and attractiveness will all affect the vulnerability risk. Similarly, the risk of accidental threat varies depending on geographical location, proximity to the area of danger, and weather conditions. Most accidental risks can be attributed to human error and malfunction. The likelihood of any added risk should be calculated accordingly. Security scanners that detect malware on USB flash drives may cause data processing to be halted temporarily.
