cited By 7; To measure the long term retention and seasonal dynamics of an initial 4 kg addition of 133Cs into an 11.4-ha, 157,000 m3 reservoir (Pond 4, near Aiken, South Carolina, USA), the concentrations and inventories of 133Cs in the water column

An uptake parameter u (Lkg(-1)d(-1)) and a loss rate parameter k (d(-1)) were estimated for the patterns of accumulation and loss of (133)Cs by three fish species following an experimental (133)Cs addition into a pond in South Carolina, USA. These u

The probable occurrence and rate of foliar absorption of stable cesium (133Cs) from the water column by aquatic macrophyte species was analyzed following the addition of 133Cs into a small reservoir near Aiken, South Carolina, USA. An uptake paramete

A historical perspective is given of the current paradigm that does not explicitly protect nonhuman biota from radiation but instead relies on the concept that if dose limits are set to protect humans, then the environment is automatically protected

Biodosimetry, the estimation of received doses by determining the frequency of radiation-induced chromosome aberrations, is widely applied in humans acutely exposed as a result of accidents or for clinical purposes, but biodosimetric techniques have

Understanding the processes governing a contaminant's transport is difficult in uncontrolled field experiments; however, controlled laboratory experiments are often contrived and may quickly loose realism. Knowing how well small-scaled, laboratory ex

Over 50% of the wells in the Nambe region of northern New Mexico exceed the US Environmental Protection Agency's recommended drinking water standard of 20 microg l(-1) for 238U; the highest in the area was measured at 1,200 microg U l(-1). Uranium up

The sediments of Pond A, a former Savannah River Site cooling pond for R-reactor, were contaminated with 137 Cs between 1954 and 1964. Pond A is unique because it is very shallow and contains an extremely high density of aquatic vegetation and old, u

Activity concentrations and plant/soil concentration ratios (CRs) of 239,240 Pu, 241 Am, 244 Cm, 232 Th, and 238 U were determined for three vegetable crops grown on an exposed, contaminated lake bed of a former reactor cooling reservoir in South Car

Activity concentrations of 137Cs in sediments, as well as extractable sediment concentrations of K, Na, Mg, Ca, Mn, Zn and P, pH, percent organic matter and cation exchange capacity, were used as independent variables in an incomplete principal compo
