It is up to you to decide how you want to approach this data.

Personally, I believe it to be IN THE PRECIPITATION for sure.. which means you do not want to get the rain or snow on you, and do not want to injest the fluid.. (i.e. drink the water) until levels deminish.

Nuclear plant workers release unknown amount of radioactive tritium into Mississippi River

by Ethan A. Huff | NaturalNews.com

Workers at the Grand Gulf Nuclear Plant in Port Gibson, Miss., last Thursday released a large amount of radioactive tritium directly into the Mississippi River, according to the US Nuclear Regulatory Commission (NRC), and experts are currently trying to sort out the situation. An investigation is currently underway to determine why the tritium was even present in standing water found in an abandoned unit of the plant, as well as how much of this dangerous nuclear byproduct ended up getting dumped into the river. Many also want to know why workers released the toxic tritium before conducting proper tests.

The Mississippi Natchez Democrat reports that crews first discovered the radioactive water in the plant’s Unit 2 turbine building after heavy rains began hitting the area last week. Unit 2 was a partially-constructed, abandoned structure that should not have contained any radioactive materials, let alone tritium, which is commonly used to manufacture nuclear weapons and test atomic bombs (http://www.nirs.org/radiation/triti...).

According to reports, alarms began to go off as workers were releasing the radioactive storm water into the river, which engaged the stop flow on the release pump. Neither NRC nor plant officials know how much tritium was released into the river during this release.

"Although concentrations of tritium exceeded EPA drinking water limits, the release should not represent a hazard to public health because of its dilution in the river," insisted Lara Uselding, public affairs officer at NRC Region IV, to reporters.
