This item is designed to demonstrate the stabilizing effect of neutrons on the atomic nucleus. The ""protons"" are made of disc magnets while the ""neutrons"" are made of browned iron discs. The ""protons"" will, because they are magnetized, repel one another when placed on flat surface or overhead projector. The stabilizing effect of the ""neutrons"" is illustrated by placing them between the ""protons"", thereby eliminating the repulsive force. The ""protons"" are supplied with red marking, the ""neutrons"" with blue. Supplied as single pieces. The “neutron” can be ordered under product code MO150905.

The Alpha particle Spark Detector from Frederiksen has been developed to enable visualization of alpha particles. The apparatus can be likened to a GM tube, but using atmospheric air instead of the diluted quenching gas in the tube. When alpha particles ionize the air in the spark gap of the detector, bright sparks can be both seen and heard. The apparatus incorporates a transparent lid, which allows clear observation of the sparks. The detector requires connection to safe high voltage (EHT) power supply with voltage range of 0-5 kV or 0-6 kV. The apparatus can be safely used directly on bench top or table and includes a removable threaded steel rod for mounting the unit on a radioactivity bench (RA95610) or squat retort base with thumbscrew (ST96274). • Gives clearly visible and audible response to alpha radiation • Demonstrates the ionization of air by alpha particles • Detects alpha radiation from radioactive minerals or radioactive sources • Allows study of range in air shielding by different materials
This GM counter is the most versatile and easily operated model yet. The counting time can be set to 1, 10, 60 or 100 seconds or set to manual start/stop. Counting may be set to run repeatedly and the last, complete result is displayed in the main display while new counts accumulate in the auxiliary display. The counter accepts both BNC and Jack type GM tubes. With the optional USB connection it can interface with computer and if pulse output for further hardware processing is required, that is also available. For demonstration purposes the authentic clicking Geiger-counter sound may be turned on if preferred. Other improvements over the previous model include lower overall system dead time and lower current consumption, with the unit now being powered by AA batteries. The counter may also be powered from the optional mains adapter.
A multipurpose GM tube, sensitive to alpha, beta and gamma radiation. Mounted in housing with protective cover and 10 mm diameter support rod. It is complete with integral lead and BNC connector. This GM tube does NOT have built-in anode resistor, and therefore requires counter with built-in anode resistor. Suitable for use with RA67530. • Window diameter: 9.14 mm • Recommended bias voltage: 500 V • BNC plug
This pack of 500 x 10 mm plastic cubes is used to investigate and demonstrate half-life. Each cube has one black face, the other faces all being yellow. The cubes are thrown or scattered like dice and those which land with the black face uppermost represent radioactive nuclei which have decayed. The black upward facing cubes are then removed, the remaining cubes thrown again and the process repeated. The removed cubes represent radioactive decay and decay curve can be plotted from the results.
This extra sensitive GM-tube has a large window which makes the detector well suited for measuring low activity sources. This provides more counts and thus improves counting statistics for more accurate determinations of half-lives, etc. The GM-tube housing is supplied with a protective cover as well as a protective grid in front of the window. It is sensitive to alpha, beta and gamma radiation. It is complete with a removable protective cap, holder, and integral lead with BNC plug. This GM tube does NOT have built-in anode resistor, and therefore requires counter with built-in anode resistor. Suitable for use with RA67530. • Useful diameter: 28.6 mm • Recommended supply voltage: 500 V • BNC plug
