Open symbols indicate exposed tracers and closed symbols indicate buried
tracers. Competent flow duration was estimated using published information
about flow duration exceedence frequency in Allt Dubhaig and an individual
hydrograph analysis in Carnation Creek. Published values taken from Hassan (
1990), Haschenburger (2011), and Lenzi (2004), plus original observations for
Allt Dubhaig (R. Ferguson, pers. comm., 2010). Figure 5.4 Exchange probabilities

The old maximum permissible concentrations (MPC) are to be replaced with a
new set of numbers given in appendix B of the proposed regulations as Table 1
for occupationally exposed workers, Table 2 for unrestricted areas, and Table 3
for disposal into the sewer. The values for occupational exposure to some
common waterflood tracers were abstracted from Table 1 above and appear in
Table 2.4 in this chapter. For the first time, these regulations also go into detail on
how the ...

The following factors were felt to be requirements for a suitable tracer : 1. Toxicity-
the material must be non-toxic in terms of dermal, respirable, and gastro-
intestinal exposure. 2. The tracer must be of a similar nature to pesticide in terms
of dermal exposure mechanism; i.e. the transfer properties of the tracer from
foliage to worker must be similar to those of pesticide. 3. The tracer must not
change fluorescence intensity over time, or when exposed to environmental
variables such as ...

The most commonly applied nuclides for erosion rate measurements are 3He, l°
Be, 26Al and 36Cl. Until recently, use of these nuclides was restricted to
determining denudation rates of exposed bedrock outcrops: recently, several
research groups have begun to measure nuclide abundances in sediments with
the goal of estimating basin-scale rates of denudation. 19.2.1 Cosmogenic
nuclides in exposed outcrops The abundance of a cosmogenic nuclide in a
sample of outcropping ...

Next, the sorbent is carefully extracted to quantify the mass of all contaminants
intercepted by the flux meter and the residual masses of all resident tracers. The
contaminants' masses are used to calculate time-averaged contaminant mass
fluxes, while residual resident tracer masses are used to calculate cumulative
fluid flux. Depth variations of both water and contaminant fluxes can be measured
in an aquifer from a single flux meter by vertically segmenting the exposed
sorbent ...

... Ruben, in collaboration with Hassid and Kamen," began experiments using the
short-lived carbon isotope C" (half-life, 20.5 min.). The plan of research was
simple. Green plants or algae, actively photosynthesizing CO2, were exposed to
tracer quantities of the gas labeled with C". At various times, determined by the
nature of the experiment, the plants were killed by boiling in ethanol or water. The
resulting suspension was fractionated, and the fractions were assayed for

A general guide for a mock tracer team is to follow the number and configuration
of your last Joint Commission or JCI survey team (see the sidebar “Tracers at a
Glance” on pages 5—6). However, you might want to involve more people or
have multiple mock tracer teams; try to allow as many people as possible to be
exposed to the tracer process and to learn more about the surveyors' angle on
the process. If your organization has not had a survey yet, aim for five to eight
