Radioactive Sources
Product Code : LSK-CL-10085
Radioactive Sources (SKU LSK-CL-10085) are sealed alpha, beta and gamma teaching sources, each securely encapsulated in a heat-resistant, waterproof plastic disk. Used with a Geiger counter, they let physics and chemistry students measure radioactive emissions and compare how the three types of radiation behave. They are for supervised laboratory use in colleges and senior school labs. Science Lab Supplies handles enquiries from Ambala, India, for schools, colleges, tender contractors and distributors.
Specifications
The radioactive material in each source is sealed inside a plastic disk that resists heat and water, so the material itself is not handled during an experiment. The range covers the three emission types taught in radioactivity courses: alpha, beta and gamma. The quotation states the exact sources and quantities offered.

Applications and Experiments for Radioactive Sources
Sealed sources are used with a GM counter to show that radiation can be detected, counted and stopped by different materials. They support the nuclei and radioactivity chapter of NCERT Class 12 physics, B.Sc. nuclear physics practicals and radiochemistry introductions in colleges and teacher-training institutes.
- Class 12 physics: comparing count rates from alpha, beta and gamma sources against background.
- Absorption practicals: paper, aluminium and lead as absorbers for each radiation type.
- B.Sc. practical: inverse-square law for gamma radiation.
- Determining the operating plateau of a GM tube.
These sources emit ionising radiation. Handle them only with tongs, never with bare hands, under teacher supervision; keep them in a locked, shielded store when not in use; and follow your institution's radiation safety rules. Possession and transport of radioactive sources are regulated in many countries, so check the rules that apply to you before ordering.
Standard Scope of Supply
Radioactive Sources are supplied as alpha, beta and gamma sources, each encapsulated in a heat-resistant, waterproof plastic disk. The quotation lists each source and quantity. A Geiger counter, tongs and a storage container are separate items and can be quoted on request.
Packing, MOQ and Lead Time
Tell us which of the alpha, beta and gamma sources you need and in what number. Science Lab Supplies states the packing, delivery time and price on the quotation for that quantity, and a Geiger counter or protective gloves can be added so the practical is fully equipped.
As a registered exporter holding an Importer-Exporter Code, Science Lab Supplies can ship to buyers in the Philippines, Nepal, Bangladesh, Zambia, Rwanda and South Africa, subject to the rules for radioactive material. Send questions through the contact page or the enquiry cart, and see the lab tender page for tenders.
Frequently Asked Questions
What radiation do these sources emit?
The range covers alpha, beta and gamma sources, the three emission types studied in school and college radioactivity practicals.
How are the sources sealed?
Each source is securely encapsulated in a heat-resistant, waterproof plastic disk, so the radioactive material is not exposed during normal use. They must still be handled with tongs under supervision.
What else is needed to use them?
A Geiger counter to detect the radiation, tongs for handling and a secure shielded store. Absorbers such as paper, aluminium and lead are used for comparison experiments.
Who supplies the Radioactive Sources?
Science Lab Supplies supplies them from Ambala, India, to schools, colleges and distributors, and answers enquiries about quantities and delivery through the contact page.
Related Radioactivity Items
Sealed sources are only one part of a radioactivity practical. A Geiger counter measures them, protective gloves add a layer of safe handling, and atomic models explain the nucleus the radiation comes from, so these four items are often ordered alongside the sources.
- Radiation Geiger Counter — detects and counts alpha, beta and gamma radiation.
- Gloves - Protective — hand protection during practicals.
- Model of The Atom — shows the nucleus that emits radiation.
- Atom Activity Model — student model of protons, neutrons and electrons.
