My name is Cristina P\u00e9rez Gamarra, I am a chemical engineer from the Complutense University of Madrid. Initially passionate about biotechnology, an internship at the Trillo Nuclear Power Plant changed my vocational orientation forever. After working, about seven years, at the Chemical and Radiochemistry Section of this plant (and a few more refuelling stops), I decided to give a new direction to my life and career by moving to another country. I currently work as proficiency testing coordinator at the French Authority for Nuclear Safety and Radiation Protection (ASNR) (\u201cAutorit\u00e9 de S\u00fbret\u00e9 Nucl\u00e9aire et de Radioprotection\u201d).<\/span><\/p>\n

How many years have you been in your current responsibility?<\/b><\/p>\n

I started working as a proficiency test coordinator for the Laboratory of Standards and proficiency testing (LEI) at the former IRSN (\u201cInstitut de radioprotection et s\u00fbret\u00e9 nucl\u00e9aire\u201d) in March 2022, at the Analysis and Metrology Environmental Service. I said former IRSN because, in January 1<\/span>st<\/span>, 2025, the IRSN was merged with the ASN (\u201cAutorit\u00e9 de s\u00fbret\u00e9 nucl\u00e9aire\u201d), creating the ASNR.<\/span><\/p>\n

My main role is to coordinate proficiency testing for measuring radioactivity in the environment. These tests, in which French and foreign laboratories can participate, allow to comply with the ISO 17025 standard, as we are accredited in the ISO 17043. However, the main objective is to obtain authorization for incorporating the measurements, made by these laboratories, into the national network of radioactive environmental measurements, RNM<\/a>, which is the equivalent of environmental radiological surveillance in Spain<\/a>. We also work closely with the General Directorate for Food (DGAL), which prescribes every year one of our proficiency testing.<\/span><\/p>\n

We work with seven families of matrices (water, soil, biological matrices, aerosols, food, gases, and the environment) and seventeen measurement categories. And we conduct an average of five to six proficiency testing each year.<\/span><\/p>\n

Additionally, I am the radioactive sources correspondent of my service.<\/span><\/p>\n
