Abnormally high radiation levels were detected near the border between the two Koreas days after North Korea claimed to have mastered a complex technology key to manufacturing a hydrogen bomb, Seoul said Monday.

San Francisco, California, likely will become the first U.S. city to require cell phone companies to disclose how much radiation their gadgets emit.

D.J. Soviero wanted the least treatment that would beat back her small, early-stage breast cancer, but her first doctor insisted she had only one option: tumor removal followed by radiation and chemotherapy.

Then she found a novel program at the University of California, San Francisco, that gave her an unbiased evaluation of the pros and cons of all treatment options.
"I realized that I didn't need to use a sledgehammer. It was my choice," said Soviero, of San Francisco, who went with the lumpectomy and radiation, but refused the chemo.

New full-body airport security scanners using X-rays generate much lower doses than normal background radiation, a draft report compiled by international agencies says.
