Will the pregnant women watch TV feely?

Yes. By using the LCD (Liquid Crystal Display) instead of the traditional screen, the radiation will become lower, and increase the Refresh rates which is an effective technology which will contribute more in reduce the bad influence factors for people health of watching TV especially for pregnant women. Additionally, there will be some clothes which can protect the health of babies.

"Whether childern live on a farm in Fairmont, in an apartment in Phillips, or a split–level home in Woodbury, Minnesota children live in an environment vastly different from that of previous generations. It's not Pokèmon or technology that's made the difference. It's the 80,000 man–made chemicals that touch every part of the environment, including the children themselves.

Toxins to the brain and nervous system, such as mercury and PCBS, contaminate tuna and other fish, including many Minnesota sport fish. Air pollutants like exhaust from diesel trucks and buses exacerbate children's asthma and bronchitis. Pesticide residues are widely found in some of children's favorite foods and in many drinking water systems. And pesticides — designed to kill — are regularly applied around homes and in schools.

The Minnesota Legislature is considering two bills that would help protect children from these toxins. SF2441, introduced by Sen. Ellen Anderson, would direct the Minnesota Department of Health to use children as the standard in risk assessment. HF2520, sponsored by Rep. Jean Wagenius, would give parents the right to know when pesticides are used at their children's schools.

In its landmark 1993 report, "Pesticides in the Diets of Infants and Children," the National Academy of Sciences found that children are uniquely vulnerable to environmental toxins. Pound for pound, children eat and drink more, and breathe more air than adults, so their exposures to pesticides in contaminated food, water and air can be several–fold higher.

Children's immature bodies metabolize, detoxify and excrete chemicals differently. Their brains, immune, endocrine and reproductive systems continue to grow and develop from conception to adolescence.

These delicate developmental processes are susceptible to disruption. If they are interrupted, pushed even slightly off course by exposure to toxins in the womb, during infancy and early childhood, lifelong consequences can result. Thus, children and pregnant women are at risk from chemical exposures at levels that would be safer for mature adults.

Studies in both humans and animals suggest that these low–level exposures to the young can cause subtle, but permanent damage to the brain, reproductive, immune or other organ systems that may not be apparent until later in life.

Because nearly all chemicals, including pesticides, are produced and marketed with very little testing for possible ill effects on the child's body or brain public health argues that we should exercise caution before exposing children to these chemicals.

That's why the National Academy of Sciences concluded in 1993 that in the absence of scientific data to the contrary, there should be a presumption of greater toxicity to children. Its basic message for protecting children: Better safe than sorry.

Children depend on a healthy, intact brain and nervous system to learn and become productive adults. Critical stages of brain development occurring during the first few years of life include brain cell growth, formation of connections between brain cells, and pruning of connections to assure optimal brain function.

Yet the academy found in 1993 that exposure to neurotoxic compounds at levels believed to be safe for adults could result in permanent loss of brain function if it occurred before birth or in early childhood."

"Putting Television Radiation in Perspective Man cannot escape exposure to some radiation. We are surrounded by natural radioactivity in the earth and by cosmic rays from outer space. This is called background radiation and cannot be controlled. We are also exposed to manmade radiation, which can and must be controlled.

Much of the manmade radiation people are exposed to comes from electronic products. These include diagnostic x-ray machines, television sets, microwave ovens, radar devices, and lasers. In some cases, as with diagnostic x-rays, radiation emitted from these devices is intentional and serves a useful purpose. In others, as with TV sets, radiation emitted is not intentional and is not essential to the use of the product.

Do TV Sets Give Off X-Rays? X-rays may be produced when electrons, accelerated by high voltage, strike an obstacle while traveling in a vacuum, as in a TV containing a cathode ray tube (CRT). Since many of the components in television sets operate at thousands of volts, there is the potential for x-ray generation. These components may produce x-rays capable of escaping from the television receiver or CRT. This unintentional emission of x-radiation can pose a potential hazard and must be controlled.

Is the TV Radiation a Hazard? Scientists have not identified specific health effects resulting from exposure to extremely low doses of low-level radiation over prolonged periods of time. However, the current assumption is that there is no threshold of exposure below which x-radiation may not adversely effect human health. It is advisable, therefore, that x-radiation from TV sets, as well as other commonly used electronic products, be kept as low as reasonably achievable. It was for this purpose that Congress enacted the Radiation Control for Health and Safety Act of 1968 (currently called Federal Food, Drug, and Cosmetic Act – Subchapter C – Electronic Product Radiation Control).

It should be emphasized that most TV sets have not been found to give off any measurable level of radiation, and there is no evidence that radiation from TV sets has resulted in human injury.

Setting a Radiation Safety Standard The Food and Drug Administration (FDA) has the responsibility for carrying out an electronic product radiation control program mandated by the Electronic Product Radiation Control provisions of the Food Drug and Cosmetic Act. Through it's Center for Devices and Radiological Health, FDA sets and enforces standards of performance for electronic products to assure that radiation emissions do not pose a hazard to public health.

A Federal standard limiting x-ray emissions from TV receivers to 0.5 milliroentgen per hour (mR/hr) was issued on December 25, 1969. The standard is applicable to all TV sets manufactured after January 15, 1970. The overall effect of the standard is to require that TV receivers must not emit x-radiation above the 0.5 mR/hr level when tested under adverse operating conditions. Test conditions do not represent normal use and ensure that when used under normal conditions, TV sets do not pose a radiation hazard.

Assuring That TV Sets Meet the Radiation Standard Manufacturers of television receivers and computer monitors contain CRTs must certify that their products meets performance standard under Title 21 of the Code of Federal Regulations (CFR) Part 1020.10. All TV manufacturers must submit written radiation safety reports to FDA outlining how they assure that each set coming off the assembly line complies with the Federal x-ray radiation limit. These reports contain a description of the manufacturer’s quality control and testing program and the television radiation safety design. Manufacturers also must maintain records of test data and prepare an annual report to FDA summarizing these records. The FDA has the authority to ask for radiation safety data including results of x-ray leakage from selected sets to determine compliance with the standard.

Television receivers imported into the United States, which do not meet the standard are not allowed into the country and are destroyed if not exported in 90 days. Importers, however, may petition FDA for permission to correct the violations.

How Safe Are TV Sets Today? X-radiation emissions from properly operated TV sets and computer monitors containing CRTs are well controlled and do not present a public health hazard. The FDA standard, and today’s technology, such as electronic hold-down safety circuits and regulated power supplies, have effectively eliminated the risk of x-radiation from these products. FDA has not found TVs that violate the standard under normal (home) use conditions.

It is important to note also that flat panel TVs incorporating Liquid Crystal Displays (LCD) or Plasma displays are not capable of emitting x-radiation. As such these products and are not subject to the FDA standard and do not pose a public health hazard."
