                                 INTRODUCTION
    Because of the long physical and biological half lives of many of the
transuranium ^adionuclides, because of their relatively high toxicity  and
because of thei-  increasing worldwide inventory and distribution, it is
imperative that their potential hazard to humans be assessed.  To this end, in
recent years, the Environmental Monitoring Systems Laboratory at Las Vegas,
Nevada (EMSL-LV) has carried out a series of studies on the biological
transport of plutonium, americium, neptunium, and curium in lactating dairy
cattle and goats.  Ruminants in general and cattle in particular form one of
the more important links in the human food chain.  Milk and milk products
constitute a significant portion of the human diet, especially for children.
In addition, beef, which also forms an important fraction of the diet in the
United States, is in part derived from culled dairy animals.

    This summary consists of a compilation of detailed data from a series of
previously published studies.  It has been prepared to present the data from
all of these studies in a single source to be used by regulatory agencies in
their transport modeling and hazard assessment activities.  Selected source
materials for the data presented in this document have been published either
in the Proceedings of the Nevada Applied Ecology Group (NAEG) or as EMSL-LV
publications and are listed in the References section.  The references listed
there have been categorized as "Data Base References" and "Body Weight and
Tissue Weight References."


                             METHODS AND MATERIALS
    Most of the studies covered in this report were conducted at an
experimental farm in Area 15 of the Nevada Test Site.  Pertinent experimental
parameters for individual  animals are summarized in Table 1, and each animal
is referenced to the appropriate appendix table(s) where results for the
individual animals are presented.  The radionuclide content of tissue or
biological product for each animal is expressed as a percentage of the
administered dose per gram of tissue or product.

    Oral doses were placed in gelatin capsules containing either cellulose
fiber or starch as absorbants and were administered to the animal  by means of
a balling gun.  Intravenous doses were made up to approximately 5 ml in volume
and were administered by jugular venipuncture.  No adjustments of intravenous
or oral dose were made for individual variations in animal weight.

    Prior  o beginning each experiment, animals were placed in metabolism
stalls.  Daily milk, urine, and fecal samples, as well as frequent blood

samples, were taken beginning at least 1 day prior to dosing and continuing
throughout the experimental period.   Each cow was catheterized with an
indwelling inflatable urinary catheter, and the urine was collected
through a polyethylene tube that drained into a 20-liter plastic bottle.
A polyethylene-lined pan placed under the metal grid at the rear of each stall
facilitated collection of feces.  Milk was collected with individual bucket
milkers twice daily.  Blood samples were taken by jugular venipuncture.   All
urine, milk and fecal collections were weighed and, for some of the studies,
morning and evening collections were combined into a single 24-hour composite
for each animal.  Composites were mixed by shaking thoroughly in plastic
containers.  Weighed subsamples were then taken from each composite and placed
in individual containers with formaldehyde added as a preservative.  Large
fecal collections were mixed in a 30-quart Hobart food mixer.

    The goats were maintained under conditions similar to those of the cows
but in small, elevated metabolism stalls that permitted ready access for hand
milking.  Urine was collected by catheter, and fecal pellets were collected in
a tray.  Occasionally, the pellets had to be ground in an electric meat
grinder to homogenize or mix the daily fecal collections.

    Cows and goats were sacrificed by an intravenous euthanasia solution.
Each animal was weighed at time of sacrifice and partially exsanguinated
before tissue samples were collected.  Organs and tissues were removed from
the animals within 60 minutes of sacrifice.  Extraneous adipose tissue or
muscle was trimmed from the samples, formaldehyde was added as a preservative,
and each sample was sealed in an appropriate container.  Total weights were
taken on most organs so that the percentage of the administered dose retained
by a specific tissue or organ could be calculated.  When this was not
practical, for example, in the case of muscle, bone, or blood, total nuclide
content was based on extrapolated organ weights using the respective

-------
percentage of body weiyht reported by Davis et a\_.  (1975), Smith and Baldwin
(1974), and Mathews ei al_. (1975),  Nuclide concentrations in the various bone
samples were averaged in order to estimate retention in bone.  However,
specific data for individual  bone types are reported wherever they are
available.

    Appropriate spiked standards for feces, milk, urine,  plasma, blood cells,
distilled water, and either agar or animal  tissue were prepared for ed

    Appendix B consists of 46 tables  of  data  from individual  animals.   These
data were used to prepare the comparative tables  included  in  Appendix  A.   The
tables in Appendix B are cross indexed with individual animal  parameters  shown
in Table 1 of the text.  Table 1  gives the  animal  number,  describes  the
radionuclide dose administered, and reports the daily  output  of  milk,  urine,
and feces from each animal.

        Ratios used hereafter in the series of tables on this study are the activity  ratios  normalized  to
         indicate differences in metabolism; a ratio of unity indicates the  activity ratio  in  a  sample was
         the same as that in the 238Pu and 239Pu dose administered.   Ratios  are always 2iBPu,  239Pu.
