DESCRIPTION
The 1480 WIZARD
®
3" is an automatic, 1000-sample
capacity single detector computer-controlled
benchtop gamma counter with a high efficiency
well-type detector, specially configured 75 mm solid
lead shielding, 2000 keV energy range and a unique
sample changer design. It provides industry-leading
performance in terms of background and crosstalk
reduction. A truly universal gamma counter, it is
ideal for multilabel counting applications or for
counting high energy gamma emitters, low activity
samples or environmental samples.
STANDARD FEATURES
• Detector system consists of a thallium activated,
sodium iodide crystal of the end-well design. The
crystal height is 80 mm (3.15 in.) and diameter
75 mm (2.95 in.). Special counting geometry
ensures optimal counting efficiency of any sample
volume without the need for manual setting of
counting positions.
• Radiation shielding is present for the detector
assembly and the conveyor. The detector assembly
is surrounded by a minimum of 50 mm of lead
shielding above and below. The shielding against
the conveyor is solid lead 75 mm (2.95 in.).
The shielding weight is 225 kg (495 lbs.).

• Positive sample rack information can be accomplished
by permanently labeling each rack with a bar code,
which is read when the samples in the rack are
counted. The label can be attached to the rack on
a removable clip.
• Sample ID is facilitated using two barcodes which
can be provided for each rack. Each has the capacity
for 2 digits or a special code word.

• Automatic background correction is accomplished
by automatic subtraction of background counts in
each counting region. Complete background spectra
are stored.
• High activity counting on the 1480 WIZARD reaches
maximum activity to 10,000,000 DPM (8,000,000
CPM) in normal mode for
125

Open window (15–2000 keV).
The user can customize all nuclide preset values,
including the nuclide name and ID number. Dual label
counting can use any pair included in the library.
• Energy range is 15 keV to 2000 keV.
• Gain stabilization in the optimized window setting
for each nuclide is based on the use of multichannel
analyzer techniques. The stability and reproducibility
of the results are ensured by checking resolution,
efficiency, spectrum drift and background. Efficiency
variation < 0.5% (excluding statistical counting error).
• Live spectrum display of counts, CPM or CPS values
can be displayed on screen. Counting spectrum can be
displayed or plotted on the printer. Energy scale is
linearity corrected and can be zoomed.
• Spectrum files can be automatically saved to hard disk.
They can be copied to the data logger diskette or
transmitted to another computer. Saved spectra can
also be examined off-line with separate software, e.g.
Microsoft
®
Excel.
• Hard copy can be printed of screens and protocol
contents.
• Multi-user capability stores 99 assay protocols which
can be called into use automatically with barcode clips.
• Multitasking operation environment allows simulta-
neous protocol and file manipulation while counting
is in process.
• Help utility includes full screen helps available at all
stages of operation.
• Two simultaneous counting regions enable two
nuclides to be processed simultaneously. Nuclides
can be preset or user selected. Spillup and spilldown
correction is carried out automatically. Special dual
label normalization is not needed.
• Decay correction corrects for nuclide decay in both
counting regions to any date, time or assay beginning.
Decay correction also works in normalization, e.g.
99m
Tc. Half life values are included in the nuclide
library.
• Automatic normalization is carried out by using a
normalization cassette for each defined nuclide. Waste
radioactivity can be used for any nuclide normalization. No separate normalizations for different volumes
are needed.
• Contamination guards are inherent in rack construction,
protecting the detectors from contamination. Samples
are separated from the detectors by liquid tight,
disposable sample holders.
• Decontamination facilities are freely accessible to the
user, including the conveyor, sample changer and
detectors at all stages of operation. Decontamination
is very fast and easy.
• Automatic power failure recovery enables an assay
in process to be automatically restarted after power
failures of up to 30 days.
• Date and time includes battery support for 30 days.
Internal clock can be synchronized by via PC port.
• Connections include a serial ASCII interface RS232C,
2 output terminals: a serial printer and a system PC
(external MultiCalc
®
) and a parallel printer data
connection. Printers must be able to print in MS-DOS.
They must be Epson compatible or accept PCL Level 3
commands.
• Programmable computer and printer I/O. Each RS232C
interface port can be individually programmed for data
format, baud rate and hand-shaking mode. All ports
can be de-activated.
• Datalogger enables all assay results to be automatically
stored in MS-DOS ASCII format on 1.44 MB diskettes.
Files are transportable, as .TXT files, to popular
spreadsheet programs such as Lotus
®
1-2-3 or
Microsoft Excel.
• Remote instrument control via PC port using character
based-command language is applicable for some
non-PerkinElmer Windows
®
software as well.
RIACALC WIZ SOFTWARE
RIACalc WIZ software is standard on all WIZARD
counters and includes a built-in RIA evaluation and
quality assurance program. It supports RIA, IRMA or
screening types of assays, single or dual label.
• Curve fitting techniques support all usual response
calculations such as linear interpolation, linear to
cubic regression, either unweighted or weighted, and
interpolation or RIA/IRMA model-based spline. Fourparameter logistic fit. X-axis transformations include
lin dose, log dose or lin/log dose. Response transformations are either CPM, B/Bo, logit (B/Bo), log(B),
B/T, Bo/B or T/B.
• Assay protocols (up to 99) are RIACalc RM/DMcompatible. SAVE (to floppy) and LOAD (from floppy)
functions are provided. Protocols can be passwordprotected.
• Assay recalculation and reevaluation for assays with
erroneous samples can be done without recounting.
Full editing is possible for standards, patient samples
and controls. Previously saved curves can be used in
evaluation.
• Assay counting without standard samples enables
previously saved curves to be used in evaluation.
• Multiple nuclide work is facilitated on 1480 WIZARD
counters (MIA=multi-isotope assay). Theoretically up
to 20 radionuclides can be counted simultaneously.
Raw count results as well as spillover-corrected CPM
results are reported in up to 20 discrete energy
regions. All individual nuclides are corrected for
background and nuclide decay. Heavy overlap of
spectra may occur in practice and often maximum
number of labels may be 6 or less.
• Unknown samples can include a maximum of 10
dilution groups; each can have individual (maximum
5) replicate groups. Blank subtraction is automatic.
Blank samples are either common for standard and
unknown samples, or common for all unknowns or
for same dilution group. Six standard flags.
• Control samples can be included in each protocol.
Each control file can have a maximum of 12 values.
Either individual or average values can be automatically collected, in six levels. Levy-Jennings charts can
be plotted after an assay. The maximum number of
assays is 50. The maximum number of saved values

field; factory setting is concentration. Special view
mode is provided.
• Trend files enable 12 trends from the 125 assays to be
followed. Levy-Jennings chart can be plotted after an
assay. Special view mode is provided.
• Curve editing can be done during automatic run,
before processing unknown samples. Conditional halt,
based on to the goodness of fit is provided for automatic entry to the on-screen editor during evaluation.
• Automatic outlier rejection of bad standard points can
occur according to two different criteria; difference
from mean or from standard curve. Halt for curve
edit can also be made conditional depending on
the number of outliers.
• Precision profiles and histograms are generated and
plotted after an assay.
• Result files format selectable results to be automatically saved to hard disk. They can be copied to the
data logger diskette or transmitted to an external
computer with proper software, e.g. MultiCalc.
• Special assay protocol creation is supported by
RIACalc WIZ for assays such as hepatitis screening,
RAST screenings, ratio assays such as T
