The PNRI establishes the national standards for ionizing radiation through the Secondary Standards Dosimetry Laboratory (SSDL). The SSDL is operated to ensure that:

(a) national standards for ionizing radiation in the country are developed and maintained, and
(b) radiation instruments are calibrated to give correct and accurate indications of the levels of ionizing radiation. The radiation monitoring instruments calibrated are:

• Survey Meters/Dose Rate Meters
• Contamination meters
• Personal Dosimeters
• Rate Alarm Monitors

The Philippine Dose Registry (PhilDose) is a web-based information system that contains radiation dose records of occupationally-exposed workers in the Philippines. The registry can store doses received from Gamma, Beta and Neutron radiation.

The PhilDose, is the first Dose Registry for occupational radiation exposure in the Philippines. It is currently maintained and updated by the RPSS of PNRI. The purpose of the Philippine Dose Registry is to assess exposure of workers to external sources of radiation. Currently, OSLDs (Optically Stimulated Luminescence Dosimeters) and TLD (Thermoluminescent Dosimeters) are used as personnel monitoring devices in the country.

Personal doses are reported in terms of personal dose equivalent: Hp(10) for the whole body dose, and Hp(0.07) for skin dose. They are presented in units of milli-Sievert (mSv) which is characterized by the amount of biological damage a radiation does to the tissue. The current dose limits as per national regulations are as follows:

(a) An effective dose of 20 mSv per year averaged over five consecutive years;
(b) An effective dose of 50 mSv in any single year;
(c) An equivalent dose to the lens of the eye of 150 mSv in a year; and
(d) An equivalent dose to the extremities (hands and feet) or the skin of 500 mSv in a year.
