The Philippine Nuclear Research Institute (PNRI) is a government agency under the Department of Science and Technology mandated to undertake research and development activities in the peaceful uses of nuclear energy, institute regulations on the said uses, and carry out the enforcement of said regulations to protect the health and safety of radiation workers and the general public.

[11] In the succeeding year, William G. Padolina, secretary of the Department of Science and Technology, served as the president of the 40th General Conference of the International Atomic Energy Agency (IAEA).

[23] In 2014, the PNRI Electron Beam Facility was inaugurated and the PNRI was able to conduct its first full exhibit of Filipino applications of nuclear science and technology at the 58th IAEA General Conference in Vienna, Austria[24] This division includes the Plant Mutation Breeding Facility, which aims for the improvement of mutation breeding of important crops.

The PNRI houses the Mössbauer Effect Spectrometry (MES) system, which studies nuclear structure with the absorption and re-emission of gamma rays.

On the other hand, the XRD, also an analytical technique, is used for phase identification of a crystalline material and provides information on the unit cell dimensions.

The Radiation Crosslinking Laboratory practices covalent bonding with one or more polymers and imparting improved mechanical and functional properties in the result of cross-linking products.

This facility analyzes degradation products through gel permeation chromatography and separates different molecular weight fractions by tangential flow filtration.

Another is the Radioassay Laboratory, which established the Radiological and Receptor Binding Assay (RBA); a method used for measuring toxicity in red tide.

The Nuclear Materials Research Facility uses gamma ray spectrometers to observe particles found in a certain concentration or venue.

Through irradiation caused by Electron Beams, it is used for the sterilization of food and medical devices as well as for refining electrical components such as wires and semiconductors.

It is multi-purpose gamma ray irradiator which may be used for various applications such as elimination of harmful bacteria, improvement of agriculture and sterilization of equipment.

The Cytogenetic Analysis for Radiological Reassurance is for the monitoring or calculation of accidental or occupational exposure of clients who are exposed to gamma radiation through blood sampling.

The Engineering Services of the PNRI offers Instrument Repair Diagnostics, Decommissioning of Cobalt-60 Teletheraphy Machine, and Radioactive Waste Management.

These include provisions of training courses in the field of nuclear science and technology, radiation safety, and non-destructive testing techniques.

Regulation or eradication is performed by collecting pests, such as fruit flies, and then exposing them to gamma radiation in order to sterilize them.

[30] The PNRI developed a polyvinylpyrrolidone carrageenan dressing: a fully permanent gel in a form of a sheet that is 3-4mm thick and containing over 90% water, used to treat burns, wounds, and bedsores.

It is made from polyvinylpyrrolidone, a water-soluble polymer, and carrageenan, a seaweed polysaccharide, by means of radiation processing to effect cross-linking and sterilize the product into a final form.

[33] The PNRI also took environmental radioactivity measurements following the 2011 Fukushima Daiichi nuclear disaster as part of its radiological surveillance program for public protection and safety.

[34] In the 1990s, the PNRI identified rare-earth element (REE) deposits in northwestern Palawan through earlier geo-chemical surveys and studies.

From 2013 to 2016, the PNRI undertook a combined verification stream sediment and radiometric survey to identify and recommend a detailed evaluation of prospective sites.

The collected samples were analyzed for REE and thorium using X-ray fluorescence (XRF) and uranium determination using fluorimetry, including atomic absorption spectroscopy for other trace elements of economic value.
