我跟我姐姐也特别亲，小时候两个人还打打闹闹， 长大了就好多知心话可以说，尤其是我们俩都在美国，她也刚生了老二，我们几乎每天打电话交流。所以，我挺想下面给宝宝生个妹妹，她们以后可以互相照应的多一些。

橙橙好天使啊！

Radiation Lab Set To Detect Contamination From Japan

SAN FRANCISCO: Air Quality Management Ready To Monitor Air...

SAN FRANCISCO -- The nuclear disaster in Japan is prompting concern about the possibility of radiation fallout reaching the West Coast of the U.S.

In Northern California, the government has three radiation detection instruments: one in San Francisco, one in San Jose, and one in Sacramento.

The instruments are operated by the Enviromental Protection Agency's National Air and Radiation Laboratory.

Radnet, as it's called, can detect minute changes in radiation levels across the country.

Eric Stevenson of the Bay Area Air Quality and Managment District said the system is capable of reading radiation levels on a real time basis.

"And there are filter media inside the instrument that we send to the laboratory twice a week," explained Stevenson.

The devices can pick up traces of beta and gamma particles as well as uranium and plutonium. Following the explosions at the Japanese nuclear plant, particles would likely get picked up by the jet stream, the fast moving current of air that travels from Asia to the West Coast.

But experts said they believe any radioactive material will diminish by the time it reaches California.

"So until somebody says evacuate or whatever, I just have to wait and see."

Stevenson said right now there were no radiation concerns.

How sensitive is the measuring equipment? KTVU was told it was able to detect tiny levels of radiation from recent nuclear tests in North Korea.

啊哈，我们也是。。。我爸爸妈妈和我婆婆是在我们这里才第一次见的面，那还是生11的时候。

yeah, good for you... 你妹妹好细心！you are so lucky!
