Amplifiers
-
The amplifier is one of the most important components in a pulse processing system for applications in counting, timing, or pulse amplitude (energy) spectroscopy, providing the pulse-shaping controls needed to optimize the performance of the analog electronics.

Gross Gamma Screening System
-
The Gross Gamma Screening system is intended for the rapid screening of urine samples for the presence of elevated radioactivity in a post-radiological event scenario. This system allows up to eight urine samples to be counted simultaneously in discretely shielded 3” x 3” NaI Well radiation detectors to quickly identify elevated radioactivity from personnel in the exposed population. This screening process provides critical information to Emergency Response Agencies and is accomplished with minimal operator training.

Counters, Timers, And Ratemeters
-
ORTEC offers the broadest range of nuclear counters, timers, rate meters and multichannel scalers. Counters simply count the number of input pulses received during the counting period. Timers count pulses generated by an internal or external clock and are used to measure elapsed time, or to establish the length of the counting period. Rate meters provide a readout of the pulse count rate. Multichannel scalers count the number of events that occur during a specified time interval, referred to as the dwell time, resulting in a time-histogram of counts. “Standalone” and programmable computer controlled versions are available.

Single Channel Analyzers
-
A single channel analyzer (SCA) produces an output logic pulse on the condition that the peak amplitude of its input signal falls within the pulse-height window that is established with two preset threshold levels. ORTEC provides two basic types or classifications of SCAs: non-timing SCAs and timing SCAs. Non-timing SCAs produce an output pulse if the input signal is within the window settings. Timing SCAs produce an output logic signal precisely related in time to the occurrence of the event being measured.

Application Software
-
Application software is a key element of a premium measurement system. Applying this software approach to a broad range of radiation detector hardware and data acquisition systems, ORTEC software offers comprehensive nuclear measurement solutions that provide integrated hardware control, analysis, and display in a single, easy-to-use package.

Gross Alpha/Beta Measurement Systems
-
Gross alpha/beta measurement is one of the simplest radioanalytical procedures which are applied widely as a screening technique in the field of radioecology, environmental monitoring and industrial applications. This procedure has been developed to determine whether radionuclide specific analysis is required to further characterize the water. Regular measurements of gross alpha and gross beta activity in water may be invaluable for early detection of radioactive contamination and indicate the need for supplemental data on concentrations of more hazardous radionuclides.

Compton Suppression Counting Systems
-
Compton-Suppression Systems are used to reduce the background continuum for low-background counting, thus improving the Minimum Detectable Activity and overall spectrum quality – particularly for small volume samples such as air filters and petri dishes.

High Purity Germanium (HPGe) Radiation Detectors
-
Semiconductor based photon radiation detectors have been evolving for over half a century, with ORTEC pioneering commercial availability for a majority of that time. Initial offerings were based around lithium-drifted germanium Ge(Li) and lithium-drifted silicon Si(Li). Ge(Li) was later replaced with more advanced, high purity germanium (HPGe) detectors. ORTEC provides a comprehensive suite of HPGe detector solutions covering an extensive range of energies and for a variety of applications.

Delays And Gates
-
Delays, Gate and Delay Generators, Logic Modules, and Linear Gates are used in many research or teaching experiments and in non-research applications such as actively shielded spectroscopy systems. Delay modules allow the alignment in time of signals from different paths, so that a logical decision can be made within a logic module which will often result in an electronic go/no-go decision as to whether a particular detector analog output will be processed within an associated multichannel analyzer.

Silicon Charged Particle Radiation Detectors
-
ORTEC introduced the first silicon surface barrier detectors for charged particle spectroscopy in the early 1960’s. Since then, ORTEC has expanded the product line with more than ten different options to choose from.
