NPL facilities are equipped with a variety of radiation detection systems, including:

A wide collection of open and closed radioactive sources are available for detector testing and calibration.

Standard chemical laboratory equipment is in place for sample preparation (including grinders, mortars, sieves, conventional and high-precision balances, ordinary and high-temperature heaters, a hot bath, a pellet press, an air pump etc).

An electronics lab is installed for the development and optimisation of NPL detection systems.

The Archaeometry Center at NPL operates in the frame of the Network of Research Supporting Laboratories of the UoI, providing analytical services to research groups from different disciplines.

A super low-level background liquid scintillation analyzer (Tri-Carb 3170TR/SL - PerkinElmer Inc) is installed at the Archaeometry Center, capable of measuring tritium concentrations for radiation protection applications and groundwater studies. A lower limit of detection down to 1 TU is achieved through a specially designed electrolysis line (typical tritium levels in natural waters range from 5 to 15 Tritium Units, TUs, 1 TU=0.12 Bq/L). A Thermoluminescence (TL) and Optically Stimulated Luminescence (OSL) reader (model Risø TL/OSL DA-20) is also in operation for dating archaeological artifacts (mainly ceramics and flint stone tools) and geological samples.

A home-built Energy-Dispersive X-Ray Fluorescence (EDXRF) spectrometry arrangement is operating at NPL. Annular radioisotopic sources (¹⁰⁹Cd and ²⁴¹Am) are used for sample excitation, while detection of fluorescent X-rays is performed by a Si(Li) detector (Canberra SL80175), coupled with electronic units for signal processing and data acquisition.

The XRF Spectrometry Unit at NPL operates in the frame of the Network of Research Supporting Laboratories of the UoI, providing analytical services to research groups from different disciplines. Most commonly analyzed samples include synthetic organometallic compounds, metal oxides, metals and alloys, soils and sediments, plant and animal tissues, archaeological ceramics and glass artifacts.

Members of NPL have strong collaborations with the groups of Dr. Anastasios Lagoyannis and Dr. Michael Axiotis from the Institute of Nuclear and Particle Physics, NCSR "Demokritos" in three research areas: the study of charged particle reactions for Ion Beam Analysis (IBA), neutron-induced reactions for various energy and non-energy applications, and nuclear astrophysics studies, primarily focused on p-process nucleosynthesis.

Members of NPL hold leading roles within the n_TOF collaboration, engaging in numerous on-going and successfully completed projects. These projects focus on studies of neutron-induced fission reactions, (n,cp) reaction studies for nuclear astrophysics, nuclear medicine, fusion technology, and neutron capture reaction studies of interest in nuclear astrophysics.

At ISOLDE facility, NPL makes a significant contribution through nuclear spectroscopy studies, primarily conducted using Coulomb excitation and transfer reaction studies at MINIBALL, T-REX, and ISIS.

NPL members are actively involved in several ongoing and successfully completed projects at the Dynamitron Tandem Laboratory of the Central Unit for Ion Beams and Radionuclides of the Ruhr-University Bochum. The projects focus on the study of proton and alpha capture reactions relevant to p-process nucleosynthesis, alongside the study of charged particle reactions for Ion Beam Analysis (IBA).
