TEL-I137
The Cs-137/Ba-137m Isotope Generator has been designed for use in experiments in schools and universities to demonstrate the properties of radioactive decay. Based on the original Union Carbide patented design, it offers exceptional performance combined with ease of use and safe operation.
Each generator contains 10µCi. Of Cs-137, which represents one Exempt Quantity, making it free from specific State and NRC licensing. The generator can produce up to 1000 small aliquots of the short-lived Ba-137m isotope with a half-life of 2.6 minutes. 250ml of eluting solution is supplied with each generator and additional quantities may be ordered. This also includes 25 extra planchets.
TEL-DCC600
The TEL-DCC600 Diffusion Cloud Chamber is a device that can be used to view high energy alpha particles, lower energy beta particles, and electrons that are produced from such sources as radioactive material, cosmic rays, and other forms of naturally occurring radiation.
Unlike most cloud chambers on the market, this unit does not use dry ice! Simply connect the unit to a source of cold running water, or use the included pump and a container to recirculate ice water for hours of continuous use!
With most cloud chambers, it is often necessary to purchase other equipment for proper operation. Whether it is a source of illumination, or a high voltage power supply, this just adds to the overall cost and increases the time and complexity of operating the cloud chamber! With the TEL-DCC600 Diffusion Cloud Chamber, a high voltage source and illumination source is built in.
With visible tracks showing in as little as 15 minutes, the TEL-DCC600 Diffusion Cloud Chamber is a wonderful demonstration tool that can be easily set up and operated just about anywhere!
The TEL-DCC600 Diffusion Cloud Chamber includes the Cloud Chamber, recirculating pump and hose, 12V DC power supply, built in illuminator, an internal clearing field generator as well as the Pb210 radioactive source which is redeemable, at no extra cost, via the included coupon from Spectrum Techniques.
TEL-400DCCSYS
Our diffusion cloud chambers have large viewing areas and are continuously sensitive, and provide an enthralling view of the subatomic world.
The chamber creates a volume of supersaturated alcohol vapor that condenses on ions left in the wake of charged particles. This is accomplished by establishing a steep vertical temperature gradient with dry ice. Alcohol evaporates from the warm topside and diffuses toward the cold bottom. The gravitationally stable temperature distribution permits a layer of supersaturation near the chamber bottom. Tracks of alcohol droplets indicate trajectories of charged particles, since each ion becomes a nucleation site for droplet condensation.
TEL-400LHCCSYS
This chamber has a viewing area measuring 51 x 51 cm. Fourteen kg of dry ice and 500 ml of ethanol will operate this chamber for 8 hours. Includes a source port as well as Alpha (2% alloy of natural thorium), Beta (10 microcurie carbon-14) and Gamma (5 microcurie cesium-137) sources.
TEL-ST365S-A or B
The ST365 Radiation Counter provides new technology in nuclear lab systems for studying the characteristics of radiation.
The ST365 will support GM detectors, as well as scintillation detectors, with the use of an internal preamplifier and high voltage supply - for use as a gamma counter for wipe testing and other gross gamma measurements.
The ST365 is able to operate standalone or using a computer (PC or Mac) via USB, Ethernet connection, or WiFi. Mobile devices may connect via WiFi. This allows for data to be collected and displayed on the screen in either analog or digital format. The control software stores data in a format that can easily be transferred directly to many common spreadsheet programs.
The Intermediate PLUS Nuclear Lab System also come with a set of 5 U.S. NRC exempt quantity sources (RSS5): 1 alpha, 2 beta and 2 gamma emitters. This allows users to study the characteristics of different types of radiation.
TEL-UCS30 Systems
The Advanced Spectroscopy System for USB includes the Universal Computer Spectrometer with software in a 1K, 2K or 4K version, TEL-SP38 complete scintillation probe with stand, base and cable, TEL-RSS8 set of 8 radioactive sources including an "unknown", and the "Experiments in Gamma Spectroscopy" manual (on CD).
