The
...
RESRAD-BIOTA
...
code
...
was
...
designed
...
to
...
be
...
consistent
...
with,
...
and
...
provide
...
a
...
tool
...
for,
...
implementing
...
the
...
...
...
...
...
for
...
Evaluating
...
Radiation
...
Doses
...
to
...
Aquatic
...
and
...
Terrestrial
...
Biota
...
(
...
terrestrial, freshwater and riparian organisms are considered).
...
The
...
code
...
was
...
developed
...
by
...
Argonne
...
National
...
Laboratory
...
(ANL).
...
Code
...
and
...
version
...
control
...
are
...
currently
...
maintained
...
by
...
DOE
...
through
...
ANL as
...
part
...
of
...
the
...
RESRAD
...
family
...
of
...
codes. RESRAD-BIOTA
...
was
...
developed
...
to
...
replace
...
the
...
BCG
...
(biota
...
concentration
...
guidelines)
...
calculator
...
(although
...
the
...
latter
...
is
...
still
...
available
...
from
...
USA
...
government websites
...
it
...
is
...
our understanding that it will not be maintained).
RESRAD-BIOTA is available free of charge and can be downloaded from the following link.
An updated version of the code new version (V.1.5),
...
which
...
has
...
probabilistic
...
analysis
...
capability
...
that
...
allows
...
users
...
to
...
conduct
...
uncertainty
...
analysis
...
on
...
most
...
input
...
parameters,
...
was
...
released
...
in
...
December
...
2009.

...
The
...
RESRAD-BIOTA
...
package
...
is
...
designed
...
as
...
a
...
screening
...
tool
...
with,
...
in
...
effect,
...
a
...
requirement
...
for
...
site
...
specific
...
data
...
at
...
anything
...
above
...
the
...
initial
...
screening
...
levels.
...
However,
...
the
...
tool
...
does
...
contain
...
allometric
...
models
...
enabling
...
the
...
user
...
to
...
define
...
transfer
...
to
...
terrestrial/riparian
...
mammal
...
and
...
bird
...
species
...
of
...
interest
...
including
...
the
...
creation
...
of
...
simple
...
foodchains
...
(see
...
...
...
...
).
...
The
...
RESRAD-BIOTA
...
code
...
has
...
been
...
applied
...
by
...
both
...
the
...
code
...
developers
...
and
...
independent
...
users
...
in
...
intercomparison
...
exercises
...
of
...
the
...
IAEA's
...
...
programmes.
