Forme noi de cancer

Zi de zi apar noi forme de cancer. Medicii nu stiu de ce. Este vorba de dispozitive electronice setate pe o anumita frecventa inalta insa nu extrem de inalta care stimuleaza dezvoltarea celulelor cu viteza mai mare decat este natural. Nu recomand sa cautati ”schema dispozitiv care provoaca cancer” deoarece riscati sa fiti urmarit. Aceste dispozitive de atac care provoaca cancer chiar daca sunt cumparate sau produse artizanal opereaza pe aceleasi frecvente. Pot fi bruiate cu dispozitive care se gasesc de cumparat pentru toata lumea nu doar pentru institutii guvernamentale pe www.policam.ro. Nu este nicio lege care interzice folosire acestor dispozitive, acestea respecta toate reglementarile nationale si internationale. Chiar si antenele de telefonie, retelele wi-fi, cuptoarele cu microunde pot cauza cancer insa acestea nu sunt facute special pentru imbolnavire. Sporul de antena pe care il primiti nu ajuta cu nimic la vindecare. Este obligatoriu ca valoarea SAR sa fie afisata, insa cunoasterea acestei valori nu ajuta la vindecare sau prevenire.  Voi descrie niste site-uri de pe internt si activitatile lor. Mare parte din ele solicita bani si donatii. Fie ca este vorba de donatii pentru bolnavi sau de bani pentru tratamente inselatoare sau tratamente cu efect slab consider ca sunt niste mincinosi. Sa nu mai vorbim de cazurile cand baga banii in buzunar sau in canale tv care sunt pentru propaganda politica si alte scopuri rele. Sunt si site-uri care ofera informatii gratuit pentru vindecare si prevenire. Sunt de parere ca sunt pentru vizualizari. Sa spun si eu o gluma cu ei daca ei glumesc cu asa ceva de grav cum este cancerul. Scrie ca nucile sunt bune la cancer. Sunt bune sa-ti faca coliva!
Puteti face cancer pulmonar, cancer de colon, cancer de piele, cancer osos si cancer sanguin. In toate situatiile chinurile sunt groaznice.
Vedeti ca sunt foarte multe cazuri de imbolnavire cu cancer si ca apar noi tipuri de cancer pe zi ce trece. Intrati pe policam.ro si incercati un dispozitiv care poate preveni si poate rula programe de vindecare complexe care incetinesc dezvoltarea celulelor bolnave pana se ajunge la vindecare.

Pretul pleaca de la 150 lei. Pentru aceasta suma merita sa cumparati aceste produse care sunt foarte bune si nu implica administrarea de medicamente care pot face mai rau!


Explicatia SAR - Specific absorption rate

SAR (rata absorbţiei specifice de energie ) reprezintă cantitatea de energie corespunzătoare undei de radiofrecvenţă absorbită de corpul uman în timpul folosirii telefonului mobil, valoarea limită admisă a SAR fiind de 2W/kg. Cu cat valoare SAR emisa de catre telefon este mai mica, cu atat radierea la care este supus corpul uman este mai scazuta.
“Conform Ordinului de Ministru nr.125 din 14 aprilie 2003, importul sau comercializarea de telefoane mobile sunt permise numai după includerea în instrucţiunile de utilizare ale aparatului şi afişarea la locul de vânzare a următoarelor categorii de informaţii:
Rata absorbţiei specifice de energie (SAR) care reprezintă cantitatea de energie corespunzătoare undei de radiofrecvenţă absorbită de corpul uman în timpul folosirii telefonului mobil;
– valoarea limită admisă a SAR, respectiv 2W/kg;
– valoarea SAR  a modelului de telefon mobil respectiv;
-specificaţii referitoare la expunerea consumatorului la câmpuri electromagnetice, în condiţiile prevăzute în art. 11 din Hotărârea Guvernului nr. 88/2003 privind echipamentele radio şi echipamentele terminale de telecomunicaţii şi recunoaşterea mutuală a conformităţii acestora.”
De ce nu se tine cont de aceste precizari? Sa fie valorile mai mari decat este normal?
Radiatia emisa de telefoanele mobile poate interfera cu unele cardiostimulatoare, pot aparea alterari sau distrugeri la nivelul ADN-ului, afecteaza buna functionare a celulelor si ma oresc aici dar ar mai fi multe de spus la acest capitol.
Principalele simptome ce pot aparea din cauza radiatiei emise de catre telefonul mobil:
– oboseala, dureri de cap, usturimi ale pielii, senzatia de cald in jurul urechii, etc.

Specific absorption rate (SAR) is a measure of the rate at which energy is absorbed by the human body when exposed to a radio frequency (RF) electromagnetic field; although, it can also refer to absorption of other forms of energy by tissue, including ultrasound. It is defined as the power absorbed per mass of tissue and has units of watts per kilogram (W/kg).
SAR is usually averaged either over the whole body, or over a small sample volume (typically 1 g or 10 g of tissue). The value cited is then the maximum level measured in the body part studied over the stated volume or mass.

Calculation

SAR for electromagnetic energy can be calculated from the electric field within the tissue as:
\text{SAR} = \frac{1}{V}\int_\textrm{sample} \frac{\sigma(\mathbf{r}) |\mathbf{E}(\mathbf{r})|^2}{\rho(\mathbf{r})} d\mathbf{r}
where
\sigma is the sample electrical conductivity
E is the RMS electric field
\rho is the sample density
V is the volume of the sample
SAR measures exposure to fields between 100 kHz and 10 GHz (generally known as radio waves).[3] It is commonly used to measure power absorbed from mobile phones and during MRI scans. The value will depend heavily on the geometry of the part of the body that is exposed to the RF energy, and on the exact location and geometry of the RF source. Thus tests must be made with each specific source, such as a mobile phone model, and at the intended position of use.

Mobile phone SAR testing

When measuring the SAR due to a mobile phone the phone is placed at the head in a talk position. The SAR value is then measured at the location that has the highest absorption rate in the entire head, which in the case of a mobile phone is often as close to the phone's antenna as possible. Various governments have defined maximum SAR levels for RF energy emitted by mobile devices:
  • United States: the FCC requires that phones sold have a SAR level at or below 1.6 watts per kilogram (W/kg) taken over the volume containing a mass of 1 gram of tissue that is absorbing the most signal.
  • European Union: CENELEC specify SAR limits within the EU, following IEC standards. For mobile phones, and other such hand-held devices, the SAR limit is 2 W/kg averaged over the 10 g of tissue absorbing the most signal (IEC 62209-1).
  • India: switched from the EU limits to the US limits for mobile handsets in 2012. Unlike the US, India will not rely solely on SAR measurements provided by manufacturers; random compliance tests are done by a government-run Telecommunication Engineering Center (TEC) SAR Laboratory on handsets and 10% of towers. All handsets must have a hands free mode.
SAR values are heavily dependent on the size of the averaging volume. Without information about the averaging volume used, comparisons between different measurements cannot be made. Thus, the European 10-gram ratings should be compared among themselves, and the American 1-gram ratings should only be compared among themselves.

MRI scanner SAR testing

For Magnetic Resonance Imaging the limits (described in IEC 60601-2-33) are slightly more complicated:

Short duration SARThe SAR limit over any 10 s period shall not exceed two times the stated values
Note: Averaging time of 6 minutes.
(a) Local SAR is determined over the mass of 10 g.
(b) The limit scales dynamically with the ratio "exposed patient mass / patient mass":
NORMAL OPERATING MODE: Partial body SAR = 10 W/kg – (8 W/kg * exposed patient mass / patient mass)
FIRST LEVEL CONTROLLED OPERATING MODE: Partial body SAR = 10 W/kg – (6 W/kg * exposed patient mass / patient mass)
(c) In cases where the orbit is in the field of a small local RF transmit coil, care should be taken to ensure that the temperature rise is limited to 1 °C.

Criticism

SAR limits set by law don't consider that the human body is particularly sensitive to the power peaks or frequencies responsible for the microwave hearing effect. Frey reports that the microwave hearing effect occurs with average power density exposures of 400 μw/cm2, well below SAR limits (as set by government regulations).
Notes:
In comparison to the short term, relatively intensive exposures described above, for long term environmental exposure of the general public there is a limit of 0.08 W/kg averaged over the whole body.[3] A whole-body average SAR of 0.4 W/kg has therefore been chosen as the restriction that provides adequate protection for occupational exposure. An additional safety factor of 5 is introduced for exposure of the public, giving an average whole-body SAR limit of 0.08 W/kg.

FCC advice

The FCC Guide, "Specific Absorption Rate (SAR) For Cell Phones: What It Means For You," after detailing the limitations of SAR values, offers the following "bottom line" editorial:
"ALL cell phones must meet the FCC’s RF exposure standard, which is set at a level well below that at which laboratory testing indicates, and medical and biological experts generally agree, adverse health effects could occur. For users who are concerned with the adequacy of this standard or who otherwise wish to further reduce their exposure, the most effective means to reduce exposure are to hold the cell phone away from the head or body and to use a speakerphone or hands-free accessory. These measures will generally have much more impact on RF energy absorption than the small difference in SAR between individual cell phones, which, in any event, is an unreliable comparison of RF exposure to consumers, given the variables of individual use."

MSBE (minimum SAR with biological effect)

In order to find out possible advantages and the interaction mechanisms of Electromagnetic fields (EMF), the minimum SAR (or intensity) that could have biological effect (MSBE) would be much more valuable in comparison to studying high intensity fields. Such studies can possibly shed light on thresholds of non-ionizing radiation effects and cell capabilities (e.g., oxidative response). In addition, it is more likely to reduce the complexity of the EMF interaction targets in cell cultures by lowering the exposure power, which at least reduces the overall rise in temperature. This parameter might differ regarding the case under study and depends on the physical and biological conditions of the exposed target.
