Sealed Radioactive Source, Cobalt Manufacturer,Supplier and Exporter in India

Sealed Radioactive Source, Cobalt (Product Code: SLE/PHY/289) is a 5 µCi (185 kBq) cobalt-60 teaching source used to demonstrate gamma radiation in school and college physics laboratories. An aluminium disc over the active material absorbs the beta particles, so only gamma rays leave the source, and the mount is colour-coded green. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, for nuclear physics lab equipment set-ups in India and international markets.

Specifications

What Is the Cobalt-60 Source Used For?

Because the beta component is filtered out, the cobalt source gives a clean gamma beam for the parts of a radioactivity course that alpha and beta sources cannot cover. With a Geiger-Muller tube and counter, students show that gamma rays pass through paper and aluminium almost unchanged and are reduced only gradually by thickening layers of lead. Moving the detector away in measured steps lets them test the inverse-square law, and a magnet placed in the beam shows that gamma rays, unlike beta particles, are not deflected.

Good practice follows the time, distance and shielding rule. Lift the source by its 4 mm stem with tongs, point the window away from people, take readings promptly, and return the source to its lead castle and labelled box straight after use. Keep a written log of each use, store the box in a locked cupboard, and remember that with a 5.26-year half-life the count rate drops noticeably over several years of teaching.

What to Specify When Ordering

• Quantity of cobalt-60 sources, and whether strontium or americium sources are needed as well.
• Any registration or authorisation reference your institution holds for sealed radioactive sources.
• Whether a GM tube holder, counter or scaler should be quoted with the source.
• Full delivery address and country, as transport rules for radioactive material vary.

Supplier

ScienceLab is the trading name of Jain Scientific Equipments Private Limited in Ambala, Haryana, India. The company sources this cobalt-60 teaching source for schools, colleges and institutes, and can quote it together with the detectors and counters used in the same practical. Because radioactive sources are controlled materials in most countries, we confirm documentation and delivery requirements with each buyer before supply. See our company profile for more about us.

Frequently Asked Questions

What radiation does the Sealed Radioactive Source, Cobalt emit?
The Sealed Radioactive Source, Cobalt emits gamma radiation only. Its cobalt-60 is covered by an aluminium disc that absorbs the beta particles, so the source is well suited to gamma penetration, lead absorption and inverse-square law experiments.

What are the activity and half-life of the Sealed Radioactive Source, Cobalt?
The Sealed Radioactive Source, Cobalt holds 5 µCi (185 kBq) of cobalt-60, which has a half-life of 5.26 years. Its activity therefore halves over that period, so note the date of receipt alongside the strength engraved on the mount.

How is the Sealed Radioactive Source, Cobalt identified and packed?
The Sealed Radioactive Source, Cobalt is colour-coded green, with its nature and strength engraved on the mount. It arrives in a small lead castle inside a labelled MDF storage box, 100 x 75 x 65 mm high, with a data sheet enclosed.

Is authorisation needed to buy the Sealed Radioactive Source, Cobalt?
Rules for holding a sealed source such as the Sealed Radioactive Source, Cobalt differ from country to country. Before ordering, check with your national radiation regulatory authority what your institution needs, and share those details with us through the contact page.

How should students handle the Sealed Radioactive Source, Cobalt?
The Sealed Radioactive Source, Cobalt should be moved only with tongs by its 4 mm stem, with the window pointed away from people. Never touch or press the gauze cap, keep exposure time short, and return the source to its lead castle immediately after readings.

Who supplies the Sealed Radioactive Source, Cobalt?
The Sealed Radioactive Source, Cobalt is supplied by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, from Ambala, Haryana, India. We quote it for schools, colleges and institutions in India and international markets, together with matching detectors and counters.
