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 set in its Ambala factory (Plot 448, HSIIDC Industrial Area, Saha, India) and sells it directly to schools, colleges, tender contractors and distributors.
Specifications
The set is deliberately simple: 500 small cubes of plastic material stand in for unstable nuclei, and a plastic cup or jar is used to shake and pour them. Trials can be repeated as often as the lesson needs, and results from several groups can be pooled.

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.
- Linking probability in mathematics with the decay constant in physics.
In a typical run students 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 graph paper or record sheets are prepared by the school.
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. Reach the team on the contact page, build a list in the enquiry cart, or see how tenders are handled on the lab tender page.
Frequently Asked Questions
Does this half-life apparatus contain a radioactive source?
No. It consists of plastic cubes and a plastic cup or jar only, and models decay by chance rather than measuring real radiation.
How many cubes are in the set?
There are 500 small plastic cubes, giving a sizeable starting sample for the first throw.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies is the manufacturer; the set is produced at its Saha, Ambala plant, and 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.
