Absorbers Set of 24 with Holder
A comprehensive set of 24 absorbers spanning the full density spectrum — from tissue paper and card through aluminium foils, sheets and plate, to lead foils and a 12mm lead block. Each absorber is stamped with its density in g/cm². Packed in a stout card box with dividers, plus plastic support plates and a source/absorber holder rack for horizontal-plane experiments.
Kit contents:
- 24 Absorber pieces, full density range
- 1 Source & absorber holder rack
- ∞ Plastic support plates for castle use
- g/cm² - Density marked on every absorber
- PDF - Radioactive source info document
- BOX - Stout card box with dividers
- PDF - Instruction Sheet
Specifications
| SKU | SE.PA0030-001 |

Source specifications (Kit SE.PA0030-001 does not contain the following products)
| Source | SKU | Type | Half-life | Notes |
|---|---|---|---|---|
| Polonium 210 | SE.PA2667-005 | α Alpha | 135days | Order on request — not stocked |
| Strontium 90 | SE.PA2667-010 | β Beta | 28.8 years | Long-term classroom resource |
| Cobalt 60 | SE.PA2667-020 | γ Gamma | 5.27 years | Practical multi-year usable life |
Due to its 138.4-day half-life, the Polonium 210 source (SE.PA2667-005) is typically unusable for experiments approximately 18 months after manufacture. We do not carry stock of this item, and it is ordered only on request with short lead times. The previously used Americium 235 is now banned from classroom use.
Safety & compliance
- Radioactive sources must be handled and stored under applicable radiation safety regulations
- For use by trained and licenced educators and laboratory technicians only
- Sources are not included in the absorber kit and must be purchased separately
- Appropriate radiation monitoring equipment should be available during all experiments
- Comply with all institutional and jurisdictional safety protocols
*Kit contains a holder for absorbers and for radioactive sources behind the absorber.
About the Absorbers Set / 24
The Absorbers Set / 24 (SE.PA0030-001) provides everything needed to conduct systematic radiation absorption experiments in a school or university physics laboratory. The kit spans the complete practical density range for classroom experiments, from lightweight tissue paper through to a 12mm-thick lead plate — allowing students to observe how absorber density and thickness affect radiation transmission for alpha, beta, and gamma sources.
Every one of the 24 absorber pieces is 50mm square and clearly marked with its density in g/cm², enabling precise, quantitative data collection. The graduated range of materials lets students construct absorption curves, determine half-value layers, and compare the penetrating power of different radiation types in a single, well-organised kit.
Key experimental applications:
- Determining the half-value layer (HVL) for alpha, beta, and gamma radiation using different absorber materials
- Comparing the relative penetrating ability of α, β, and γ radiation through a density-graduated absorber series
- Constructing absorption curves by plotting count rate against absorber density
- Demonstrating the effectiveness of lead as a gamma shielding material
- Qualitative and quantitative classroom demonstrations of radiation absorption principles
- Investigation of the relationship between absorber atomic number/density and radiation attenuation
The included source/absorber holder rack (SE.PA0031-001) positions both the radioactive source and the selected absorber in the horizontal plane, ensuring repeatable geometric alignment across all readings. Plastic support plates are included for use when operating with a castle configuration.
Radioactive sources (Alpha/Polonium 210, Beta/Strontium 90, Gamma/Cobalt 60) are available as separate variants and must be handled, stored, and used in accordance with all applicable radiation safety regulations. A PDF document covering radioactive source information is included with the kit.
