Radioactive Deposits of Nevada - USGS

2011-6-27  the thorium-uranium ratio is about 10 to 1; although no radioactive minerals are visible, it seems probable from the analyses that mona- zite is finely disseminated in the magnetite. Most uranium deposits in Nevada consist of secondary uranium minerals disseminated irregularly through fracture zones or along bedding planes.

2 天前  Tritium, on the other hand, is comparatively very radioactive and is therefore extremely rare. Technetium-99 is a man-made material used in medicine, with a half-life of 6 hours. This is a dangerous mineral, far more dangerous than naturally occurring radioactive substances. Uranium. Tritium. Technetium-99. Half-life.

Concentration of 137 Cs in brown trout was higher than in rainbow trout.. 137 Cs concentration of brown trout in a lake was higher than in a stream.. 137 Cs concentration of stream charr was higher in region with higher aerial activity.. Concentration of 137 Cs in stream charr was higher in older fish.. Difference of contamination among fishes was due to difference in diet and habitat.

Radioactive deposits in California - USGS

Reconnaissance examination by Government geologists of many areas, mine properties, and prospects in California during the period between 1948 and 1953 has confirmed the presence of radioactive materials in place at more than 40 localities. Abnormal radioactivity at these localities is due to concentrations of primary and secondary uranium minerals, to radon gas, radium (?), and to thorium ...

Water quality assessment of lake water: a review ...

2016-3-24  TDS values in lakes and streams are typically found to be in the range of 50 to 250 mg/L. In areas of especially hard water or high salinity, TDS values may be as high as 500 mg/L. Volatile solids are those solids in water or other liquids that are lost on ignition of dry solids at 1020 °F (550 °C).

Field Notes - Welcome to the Lilly Center for Lakes

2020-5-13  Ponds and lakes are both inland bodies of freshwater that contain living creatures. At first glance, they seem very similar! To help determine the difference, both the depth and surface area must be considered. Lakes are normally much deeper than ponds and have a larger surface area. All the water in a pond is in the photic zone, meaning ponds ...
