A COMPLETE RANGE OF MONITORING EQUIPMENT

The result of our adventurous programme of research is a range of equipment of the highest reliability, sensivity and suitability for purpose—to match almost every type of radiation monitoring requirement where ionising radiations are encountered.

· Portable instruments:survey instruments for monitoring of gamma exposure, doserate to gammas / X-rays/betas/neutrons,surface contamination attributable to alpha,beta and gamma , and air concentrations of the radioactive gases (instrumnets complete with probes and reference sources as needed).

· Installed instrumentation : area and process monitors for gamma radiation, air particulate and release of materials and waste out of controlled areas.

· Personel monitors : for alpha, beta and gamma and fissionable material. Used variously at site exits, main changerooms , sub changerooms, temporary work areas and specialised laboratories.

· We also manufacture high stability reference dosemeters for calibrating radiation beams or other equipment.

· Also laboratory instruments including single and dual channel spectrometers for routine measurement and analysis of samples.

· Our recent new developments include new scintillation detectors, and new instruments for precision radiological dosimetry, personel monitoring, area surface monitoring and contamination monitoring.

DAY-BY-DAY ACTIVITIES İN NE TECHNOLOGY

Every day, like their customers, NE Technology routinely work with radioactive materials, practise radiation measurements and carry out safety monitoring.

· Ion chambers are calibrated for use in cancer treatment.

· Gamma sources are loaded into heavily shielded containers, for industrial applications.

· Instruments and probes are tested to high precision, treceable to National Physical Laboratory standards.

· Waste material is monitored for safe disposal, under the supervision of our Radiaion Protection Adviser.

· We practise area and personel monitoring, because safety and security are under the same legislation as for any other nuclear site.

This continuous hands-on experience ensures a full awareness of the finets points of good instrument design. It also explains why our detectors are designed and manufactured from raw materials, and tested in-house wherever possible—guaranteeing both high quality and consistent standards for our customers.

SAFEGUARDING THE QUALITY OF LIFE

Every industrially developed nation makes use of ionising radition:

· Between %15 and %20 of the world’s electricity comes from nuclear energy.

· Much of the world’s equipment for cancer therapy and medical imaging relies upon radiation techniques.

· The qualities of steeli coal and oil-bearing rocks are routinely measures using radiation.

· Radiation has proved indispensable for improving agricultural programmes (such as controlling parasites and improving crop yields)

· Techniques employing radiation are daily increasing our knowledge in the Physical and Life Sciences.

In short, radiation has been harnessed in many ways to improve our quality of life.

But uncontrolled, radiation poses a threat to health. Therefore extremely high standards of safety must be followed whenever radioactive materials are used.

Of absolutely key importance here is the continuous monitoring of designated controlled aeras where radioactive materials are used.

This is achieved using special instruments which must be highly sensitive, reliable and always suitable for their purpose.

SOLAR CELLS

Although solar cells are known for their exacting role in space research, there are many other less publicised activities in which they meet equaly demanding needs. For example, recent concern over the energy stiuation has focussed much attention on solar cells. With over %40 of received solar energy being re-emitted without contributing to our energy resources, solar energy conversion for terrestrial uses seems a fruitful area of development. Solar cells can play a major part here without adverse effects on the environment, and with other energy sources increasing radiply in price, they become a truly economic alternative.

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.
