Can Cell Phone Radiation Brain Cancer Leads


Can Cell Phone Radiation Brain Cancer Leads - WHO World Health Organization recently warned of the dangers of radiation from mobile phones are classified as "very likely risk of cancer". The agency had previously conducted a review of the effects of electromagnetic waves on human health.


The declaration is based on the evidence in the study of those who use cell phones extensively. Known, high intensity use of cell phones lead to increased risk of glioma, a malignant form of brain cancer.
Conclusions drawn the International Agency for Research on Cancer (IARC), the agency under the WHO, applies to radio frequency electromagnetic radiation in general, although most research in this area centered on cellular phone.
The findings are the culmination of the IARC meeting attended by 31 scientists from 14 countries to examine hundreds of results of previous studies that have been published about the cancer risks posed by electromagnetic fields.
Jonathan Samet, a scientist at the University of Southern California, who led the group stated, "There may be some risk, and therefore we should keep a close link between cell phones and cancer."
In the field of radio frequency refers to as "possibly carcinogenic", WHO has put them on par with about 240 other harmful agents, including low-level magnetic fields, powder, and worked as a dry cleaner.
The report found no clear mechanism for the waves cause brain tumors. Radiation from mobile phones is too weak to cause cancer by breaking the DNA, which led scientists to look for other causes.


"We found some common thread that tells us how the cancer can occur but there are gaps and uncertainties," said Samet.
Christopher Wild, Director of IARC, said that in looking at the potential implications for public health, there should be more research on long-term mobile phone use. "Pending the availability of such information, it is important to take pragmatic steps to reduce exposure such as hands-free devices or SMS," he said.

switch cell phone antenna


Unstable signal problems can sometimes be frustrating when we are in need phones to make calls function comparatively important. Signal problem is actually caused by 2 things namely, the quality of the signal from the BTS operator weak and condition of the phone itself does have a problem in it. If the signal beam BTS does not have any problems at all then surely, a problem that occurs due to the phone.


The phone is in trouble with the signal also has 2 possibilities. Problem is guilty of a software or hardware. The first step that must be done is to repair the software by tuning signal. If after tuning the signal still has particularly a problem, then the last step is to make the turn on the switch components of the antenna, RF IC, PA, Audio and more associated with weak cell phone signals.


Switch antenna is weak, it does not mean to do the turn. If it has very limited funds, then we can do the jumper switch the antenna without having to replace the IC PA.


The equipment must be prepared in advance are:



  1. Tin solder 0.3 mm following
  2. Fluid Flux
  3. Jumper cable 0.3 mm
The steps that must be done:
  1. Disconnect the phone casing to stay PCB / Board Phone
  2. Prepare a jumper cable to be connected at appropriate points in the image, precisely in the IC PA
  3. In the picture above, we do the jumpers on the phone 33XX
  4. After making jumpers, combine parts of the phone back to normal.
  5. Mobile phones can now be used to capture a better signal.
Trick antenna switch jumper this will affect the ability of dual-band mobile phone into one band only, ie 900 MHz. This trick is very useful to get around the limitations of funds. If you do not want to lose the ability to dual-band mobile phone into one band only, then the alternative is to make the turn with a new IC PA.
