ORTEC provides a comprehensive suite of HPGe detector solutions covering an extensive range of energies and for a variety of applications.
905 Series NaI(Tl) Scintillation Radiation Detectors
A gamma ray interacting with a scintillator produces a pulse of light that is converted to an electric pulse by a photomultiplier tube (PMT). The PMT consists of a photocathode, a focusing electrode, and 10 or more dynodes that multiply the number of electrons striking at each dynode. A chain of resistors typically located in a plug-in tube base assembly bias the anode and dynodes. Complete assemblies including the scintillator and PMT are available.
Personal Dosimetry
Dose Rate Meter 6150AD
The 6150AD is a calibratable dose rate measuring device in a robust, watertight die-cast aluminium housing. The built-in counter is used to measure photon radiation (X-ray and gamma radiation). As the letters “AD” in the designation indicate, the device has an analogue and digital display with automatic range switching. Warning tones and the acoustic single pulse detection are emitted via a piezo sounder, which is integrated in the housing. A connector pin of the probe socket serves as a serial interface and can be used to transfer and evaluate the device display (dose rate) to a PC. The 9-volt battery (IEC 6LR61) included in delivery lasts for approx. 3000 operating hours.
The probe socket on the left side allows for the connection of external probes. When a probe is connected, the internal counter of the 6150AD is automatically switched off and it is then measured with the detector of the probe. The 6150AD automatically recognises the probe type (e.g. display “ext 18” when connecting a probe 6150AD-18) and selects display areas and units according to the probe type. No fixed allocation between the probe and device has to be observed. The probe cable can be up to 100 m long.
Personal Radiation Detector PM1703GNA-II
Upgraded PRD PM1703xx-II Series have improved CsI(Tl) detector characteristics and fully comply with ANSI N42.32-2016.
The extended measurement range is enabled by the installed new CsI(Tl) detector with a semiconductor photomultiplier (SiPM).
* Instruments of PM1703xx-II Series were successfully tested in ORNL.
PM1703GNA-II is a gamma-neutron PRD, which has such competitive features as high sensitivity, compact size, user-friendly interface, low-energy operation, waterproof and shockproof case. The instrument can be used in both indoor and outdoor environments for detection and localization of gamma and neutron radiation sources and measurement of dose equivalent rate (DER).
Teletector Probe
The calibratable Teletector Probe 6150AD-t/E is a portable probe which, in conjunction with a dose rate meter 6150AD, is used to measure photon radiation (gamma and X-rays) in the quantity of H*(10). The two Geiger-Müller counters at the end of the telescope offer a very wide dose rate range. The counter for the low area is located behind the window in the front of the counter housing and can also detect beta radiation. Switching between the two counters is automatically done by the 6150AD. The power supply comes from the 6150AD.
The stainless-steel telescope can be continuously extended to a total length of approximately four metres. This allows a greater distance from the radiation source with a correspondingly reduced radiation exposure. It also makes measurements in hard-to-reach places easier.
As long as the button above the handle of the Teletector probe is kept pressed, the 6150AD works with its built-in counter. This allows the radiation conditions at the user’s location to be checked temporarily. An integrated short probe cable and the removable carrying strap are included in the delivery of the Teletector probe but not with the 6150AD.
X-Ray and Gamma Personal Dosimeters PM1610A
Electronic personal dosimeters of PM1610 series provide measurement of dose equivalent (DE) and dose equivalent rate (DER) of continuous and pulsed X-ray and gamma radiation in the energy range from 20 keV to 10 MeV, as well as time of dose accumulation. Instruments have audible, visual and vibration alarms to warn the user when pre-set dose/dose rate threshold levels are exceeded. Shockproof rubberized case and LCD with fluorescent backlight allows operation in harsh environment. Dosimeters are compact and easy in use and have long life built-in rechargeable battery.
PM1610 series is recommended for use by medical professionals, first responders, customs and border patrol, radiological and radioisotope laboratories, professionals exposed to pulse radiation.

.
Gamma Flood
Rigid PMMA flood phantom for the quality control of detector homogeneity and subsequent correction in gamma cameras.
The two filling and venting plugs of the Leeds Gamma Flood phantom are situated on the flat surface, not on one of the edges as with many other manufacturers. This is because filling from the edge necessitates that the phantom stands up on the opposite edge. In such an orientation, water pressure develops on the flat faces, forcing them outwards (bulging). The bulging does not easily rectify itself even when the phantom is placed flat, and so the difference in thickness causes unequal thickness of the test solution which might be mistaken for non-uniformity in the distribution of radioactivity.
Phantom for Intraoral Radiography Assessment, Testing & Evaluation
The CIRS Phantom for Intraoral Radiography Assessment, Testing & Evaluation (PIRATE) is a standard of reference for diagnostic radiology of the jaw. The phantom is designed to assist technical and clinical staff in the selection, monitoring, training and verification of scanning parameters common to intraoral radiological imaging procedures and other common dental procedures.
Our PIRATE phantom consists of maxilla, mandible and holding device. It can be mounted to included tripod with ballhead fitting for flexibility in positioning. The maxilla and mandible are hinged to allow a dental technician to place a bitewing film or other intraoral devices with a holder and image the phantom.
The phantom is constructed of proprietary tissue-equivalent materials that mimic reference tissues within 1% by linear attenuation for the dental x-ray and other dental imaging procedures.
The Model 134200 approximates the average male human jaw in both size and structure. The phantom features detailed 3D anthropomorphic anatomy including bone, sinus, maxilla, mandible, mandibular nerve and teeth. The bones contain both cortical and trabecular separation. The teeth include distinct dentine, enamel, root canal and crown. One tooth includes a fracture and a second includes a cavity.
Resolution Test Patterns
These test patterns are designed for quick quantitative assessments of the limiting spatial resolution of an x-ray system. The line pair patterns consist of a thin foil of Lead sandwiched between plastic plates. In the foil, linear slits are cut with a range of widths, these alternate with linear bars of the foil of equal width. One slit and one bar is referred to as a line pair, and the width of each group of lines is specified in terms of the number of line pairs per mm (LP/mm).
Ultrasound Phantoms
Sono Ultrasound Phantoms are relied on for training and QA testing of B-mode ultrasound systems. A selection of models supports your clinical needs, and helps you meet requirements.
TOR 18FG
TOR 18FG fluoroscopy phantom is a routine test object designed to be used quickly and easily on a regular basis (e.g., weekly/monthly) to provide an ongoing check of imaging performance, particularly those aspects which are most liable to deterioration. After an initial grey-scale check, image quality is measured simply by counting the number of details detected and the number of bar-patterns resolved in the image. An ongoing record of these numbers will reveal any trend towards deterioration in imaging performance.
