COUNT ON US FOR YOUR CALİBRATED RADİONUCLIDE SOURCES :

We are proud to announce that the Nucleus is now producing competitively priced calibrated sources are housed in arclylic plastic disks and are exempt from licensing.

In addition to the calibrated single istope sources we are now offering two multi gamma standards—the multi gamma Standard 1 (MGS-2). The MGS-1 consists of a mixture of three Europium radionuclides: Eu-152, Eu-154, Eu-155. These long lived sources are intended for determining photopeak efficiency as a function of energy in Germanium detectors. The MGS-2 is a mixed Standard source consisting of four radionuclides: Mn-54, Co-60, Sb-125 and Eu-155. This source also used for determining photopeak efficiency can be used beter for detectors with lesser resolution.

We also are taking some special orders to meet your specific needs in radionuclides. You can count on us for the most competitive prices and the highest quality in radionuclides.

PCA II Software License PCA software and decoder box to allow software operation without PCA card installed.(Requires EGA or VGA graphics.)

PCA Gamma Gamma library date base, contains 1418 records, search by KeV or nuclide, library editor program, installs in PCA-II function keypad.

WE SET THE STANDARDS ON PC BASED ANALYZERS:

The Nucleus PCA was the first plug in card to convert an IBM PC to a full feature multichannel analyzer. Following its introduction by Nucleus in 1984 this innovation revolutionized the nuclear spectroscopy market.

In keeping up with advances in microcomputers, and the diverse application of our PCA’s we have recently introduced the second generation of PCA cards – the PCA-II.

As its predecessor, the PCA-II has simple installation procedures and requires as little as a single slot in your computer. It has an onboard ADC memory, SCA, and can operate in the PHA and MCS mode. With its improved hardware and advanced interactive software the PCA-II is currently the leading PC based analyzer—and we intend to maintain that lead! Its high resolution interactive graphics, with easy to use pull down menu operation from the mouse or keyboard, bears testimony to our indepth research into its human engineering aspects.

With all the features of the PCA retained, the PCA-II has been further improved with a powerfull batch processing option to create and run your complex job tasks even from the DOS mode. It has advanced data manipulative ability and has the ability to data transfer in binary or Ascii mode, along with the capability or interfacing with lotus 123 , Dbase III ,Quattro an PC Paint.

Call or write to us and we will send you a free copy of our demo disk along with a detailed spec sheet and then you may see why the Nucleus sets the standards on PC based analyzers!!

CHERNOBYL

Cesium 134 and Cesium 137 contamination of foodstuff as a result of the Chernobyl incident is stil a major concern in many countries importing European produce.

Multichannel analyzers are excellent tools for performing low level contamination measurements as they eliminate much of the calibration and guesswork associated with single channel counting systems.

The Nucleus has adapted two of its products fort his specific application.

The low cost model 800A is now available as the model 800 AC containing special application software to compute the absolute cesium activity in Bacquerels. A smilar software application package is also available to run on PC’s in conjunction with the Personal Computer Analyzer.

We are now offering a Cs 134/Cs 137 mixed check source for energy calibration and ROI setting, and a callibrated liquid Cs 137 source for making a fixed geometry activity calibration Standard such as a Marinelli beaker.

TS-2 TUBE BASE & STAND

With the increase in Radon counting, more and more customers are asking us for a tube base assembly to hold a large Nal(TI) detector in a vertical position inside a lead shield. The TS-2 is a convenient way of solving this problem.

Actually , it’s the base plate and lower part of our WP-2000 assembly. It provides a simple way of holding your detector in your lead shield so that samples may be placed on the front face. Three meter cables are included so that the TS-2 may be located away from the analyzer.

RADON COUNTİNG FOR PROFESSİONALS

The detection and measurement of radon gas in homes has now become a major interest in the United States.many local health departments are distributing charcoal canisters to perform random sampling in their districts.

The Nucleus has been involved in this form of radon measurement since its inception. Intial systems supplied to Dr.Bernard Cohen at the University of Pittsburgh utilized our inexpensive Model 800 Multichannel Analyzer. We now offer complete single and multi-detector systems based on our popular Personal Computer Analyzer fort he IBM-PC or compatible.

Our new TC-2904R low background lead shield will accommodate most types of charcoal canisters and is of ring construction for dissasembly and transportation. Correction for moisture uptake of the exposed charcoal is taken into account with our Radon Application software. It also corrects for isotope decay from the time of sampling to measurement. This handy software package also produces a typed report of the Radon activity which may be mailed directly to the customer.

PCA-MBS TWO PCA CARDS İN A SİNGLE COMPUTER:

Now that we are seeing more PC and XT computers available with 8 card slots,we have decided to offer a system that will accommodate two PCA cards inside one computer.

The PCA-MBS (multiboard system ) consist of a priority board which also plugs into the computer, a special cable harness to connect two PCA cards, and the software package which allow independent operation of each of the PCA’s . If you have 4 card slots available,this system will convert your computer into two separate MCA’s.
