Beta Counting & Spectrometry Laboratory in Delhi: Reliable Beta Activity Analysis
AumNamah handles beta counting laboratory enquiries in Delhi for water, environmental and other project samples. Beta analysis may involve a gross activity screen or a targeted radionuclide investigation. The sample matrix and the isotope of concern determine which measurement approach should be reviewed.
Distinguish gross beta screening from isotope analysis
Gross beta counting provides an overall beta activity indication under a defined method. It does not assign that activity to every individual radionuclide. When the question concerns a named beta emitter, discuss the required radiochemical separation and counting approach. A screening result and an isotope-specific result answer different questions.
Select a suitable beta measurement approach
Depending on the target and method, beta measurements can use prepared residues or liquid scintillation techniques. Liquid scintillation methods can be relevant to low-energy beta emitters such as tritium. Strontium-90 investigations need a suitable dedicated procedure. Confirm the availability and scope of each requested isotope-specific analysis before collecting samples.
Consider matrix effects and reporting requirements
Residue mass, self-absorption and chemical interference can influence a counting result. In liquid scintillation measurements, quenching can affect the observed response. Method selection and quality control need to account for the sample composition. Provide the required activity units, detection capability and use of the report so the analytical plan addresses the actual project objective.
Preparing your sample
Explain whether you need a screening result or a named isotope measurement. Include the sample matrix, expected activity and previous results where available. Obtain instructions for volume, container, preservation and transport before shipment. Confirm any low-energy beta or radiochemical separation requirement explicitly.

Frequently asked questions
Does a gross beta result identify strontium-90?
No. Gross beta is a combined screening measurement. A strontium-90 requirement calls for a suitable isotope-specific method and confirmation of service availability.
Can a gamma scan replace beta counting?
A gamma scan is useful for suitable gamma emitters. Pure beta emitters require a measurement approach that can address their beta emissions and the sample matrix.
What is quenching in liquid scintillation analysis?
Quenching reduces the light signal produced or detected during measurement. A suitable method accounts for this effect when determining the activity of the sample.
