identify. How do you know someone is really deliverying you the tellurium,
not some metal alloy that he claims to be tellurium? Also, exposure to
tellurium could cause health issues. Don't kill yourself when trying to make
a few bucks.
Gold has great liquidity as well. |

3/21 (12:35pm): Rain water sampling results for precipitation from 3/19 10:
15am to 9:45pm is posted. Slight increase in activities are noted which may
be due to many reasons from actual increase from Japan to differing
atmospheric chemistry effects. Activity levels remain extremely low and
exposure to the public is insignificant.
3/20 (4:15pm): Rain water results show trace levels of radioactive iodine (
I131,I132), cesium (Cs134, Cs137), and tellurium... 阅读全帖 |

Iodine-131 0.165 mBq/m3
Iodine-132 0.03 mBq/m3
Tellurium-132 0.04 mBq/m3
Cesium-137 0.002 mBq/m3
Today, one of the monitoring stations in Sacramento, California that feeds
into the IMS detected miniscule quantities of iodine isotopes and other
radioactive particles that pose no health concern at the detected levels.
Collectively, these levels amount to a level of approximately 0.0002
disintegrations per second per cubic meter of air (0.2 mBq/m3).
Specifically, the level of Iodine-131 ... 阅读全帖 |

external dose不是一个concern呢，是下雨后留下来的才是concern，还有iodine 131
和tellurium 132的half-life才几天，如果现时的量不大，如果日本那边release停下
来，还不致于那么慌，怕就是怕日本的不停在release，有人留意日本那边的情况吗？
俺没留意，死也死得泰然。 |

发帖数: 2277 | 7 3/19 (10:34am): Rain fall from 3/17-2pm to 3/18-12:15pm. Preliminary results
show trace amounts of radioactive iodine (I131, I132), cesium (Cs137, Cs134)
,
and tellurium (Te132) which are not naturally occurring elements and are
assumed to originate from the Fukushima nuclear site. In context, we also
see
Be-7 (cosmogenically produced) and Pb-212 (radon daughter) which are
naturally
occurring isotopes that also show up normally in rain water. Preliminary
analysis show levels remain well below th... 阅读全帖 |

发帖数: 18685 | 8 3/20 (4:15pm): Rain water results show trace levels of radioactive iodine (
I131,I132), cesium (Cs134, Cs137), and tellurium (Te132). The amounts show
that the activity we are observing originated from one of the three
operating reactors that was shut down since I-131 and Te132 half-lives are
less than 10 days and the spent fuel from unit 4 had not operated for > 130
days. The calculated exposure to the public is so low that the consuming of
~500 liters of this water would only increase dose by ... 阅读全帖 |

an average mass fraction of 0.001 ppm in crustal rock; gold is 40 times more
abundant, platinum is 10 times more abundant, and silver and mercury are 80
times more abundant.[2] Tellurium is about as abundant as iridium, |
