    Laser Ablation

    Laser ablation is the process of removing material from a solid or a liquid surface by irradiating it with a laser beam. It depends on the nature of the material and its ability to absorb energy. When a low laser beam acts on the surface, then the surface material is heated by the absorbed laser energy and evaporates; whereas with a high laser beam, the material gets converted to plasma.

    Liquid Scintillation Counting

       A standard method for detecting and measuring radiation from beta-emitting nuclides. In this method, samples are dissolved in the solvents containing aromatic solvents and scintillators (a material that emits light when excited by an ionizing radiation).
