Apparatus for Studying the Value of the Half-Decay Period During Radioactive Decay
Product Code : SCL-PL-11850
Apparatus for Studying the Value of the Half-Decay Period During Radioactive Decay (SKU SCL-PL-11850) is a half-life simulation made up of 500 small plastic cubes and a plastic cup or jar. Repeated throws of the cubes model the random decay of nuclei, so students can find a half-life without any radioactive source. It suits senior secondary physics and chemistry and introductory college nuclear physics. Science Lab Supplies manufactures the cubes and jar as one set at its factory on Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and quotes the model directly to schools, colleges, tender contractors and distributors.
Specifications
Both parts of the half-life model, the cubes and their container, are set out in the table below. In short, 500 small cubes of plastic material stand in for unstable nuclei, and a plastic cup or jar is used to shake and pour them, so each throw removes a random share of the sample.

Applications and Experiments for the Half-Life Decay Model
The model shows that decay is random for each nucleus yet predictable for a large sample. Plotting the cubes remaining after each throw gives an exponential curve from which the half-life, counted in throws, is read directly. It supports radioactivity topics in senior secondary science and first-year college physics.
- Senior secondary physics: the meaning of half-life and exponential decay.
- Plotting remaining cubes against throw number and reading the half-life from the graph.
- Comparing class results to show how sample size affects scatter, then repeating a small-sample trial with conventional Dice.
- Linking probability in mathematics with the decay constant in physics, beside the sampling and binomial work of the Probability Kit.
In one possible run, students can shake the cubes in the cup, tip them out, remove those that meet a rule the class agrees on (for example, landing on a face they have marked), count the rest and repeat.
Standard Scope of Supply
Every set consists of the 500 small plastic cubes together with the plastic cup or jar used to shake and pour them. No radioactive material is involved, and extra sets for group work can be added to the same quotation.
Packing, MOQ and Lead Time
You may request one set for a demonstration or enough for every student group; Science Lab Supplies replies with a quotation giving packing, delivery time and price for the quantity requested. Other physics lab equipment in India for modern-physics lessons can be quoted with it.
Registered as an exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in South Africa, Qatar, Sri Lanka, Vietnam, Malaysia and Peru. Ask for the half-life model through the contact page, gather it with counters and detectors in the enquiry cart, or check the lab tender page if your institution buys through formal tenders.
Frequently Asked Questions
Does this half-life apparatus contain a radioactive source?
No. It consists of 500 plastic cubes and a plastic cup or jar only, and it models decay by chance rather than measuring real radiation, so the lesson needs no radiation source at all.
How many cubes are in the set?
There are 500 small plastic cubes, giving a sizeable starting sample for the first throw and enough throws for a smooth decay curve before only a handful of cubes remain in the cup.
Is Science Lab Supplies the manufacturer or a trader?
The decay model is produced at the Science Lab Supplies plant in Saha, Ambala, which makes the company its manufacturer. Each quotation is prepared by the company itself rather than by an intermediary.
Can several sets be quoted for a school tender?
Yes. State the number of sets and the delivery location, and the quotation will cover them item by item, with the packing, delivery time and price for that quantity shown on the same sheet.
