For 98 years, ICRP has brought together volunteer experts from around the world to advance radiological protection and protect people and the environment from the harmful effects of ionising radiation. Take a look back at 98 years of history and international collaboration.

Since 1928, our independent experts have developed recommendations that help protect people, animals, and the environment while enabling the beneficial uses of ionising radiation. You can celebrate with us by supporting us with a donation, if you're able. ow.ly/WFgj50ZtUMp

On World Biodiversity Day, we recognise that protecting people and the environment go hand in hand. Radiological protection plays an important role in safeguarding ecosystems for future generations. #ICRP #WorldBiodiversityDay #RadiologicalProtection

This week’s Dose of the Week highlights: Justification A core principle of radiological protection, ensuring every use of radiation delivers a net benefit to individuals or society. #DoseOfTheWeek #RadiologicalProtection #ICRP #Policy #RadiationSafety

On 16 March 2026, ICRP Scientific Secretary & CEO Christopher Clement received the Japan Foreign Minister’s Commendation from Ambassador Koji Yamanouchi at the Embassy in Ottawa. Read more about the ceremony and award here: ow.ly/O5zO50Yyc6v

Save the date! Join Task Group 111 on the 9th of April as they present factors governing the individual response of humans to ionising radiation. Click here for registration and more information: icrp.org/page.asp?id=709

The 22nd of March is World Water Day. Each year the United Nations assigns a theme to World Water Day. This year, the theme is "gender and water" which explores the intersection of water, gender, and sanitation. #WorldWaterDay #ICRP

In 2012, the United Nations General Assembly marked the 21st of March as the International Day of Forests. This day is for global observation and recognition of the importance of forests and the ecosystems they support. #InternationalDayofForests #IDF #ICRP

Radiation isn’t just something we create — some of it is always around us. This week’s Dose of the Week explores the idea of background radiation. #BackgroundRadiation #RadiationScience #ICRP #DoseOfTheWeek

Deputy Scientific Secretary Olga German is in #Vienna this week, updating member states on our work at the Meeting of the Commission on Safety Standards (CSS-59), advancing dialogue on international radiation safety standards.

Radioactive materials don’t just decay — the body also plays a role. This week’s Dose of the Week explores the idea behind biological half-life. #BiologicalHalfLife #RadiationScience #ICRP #DoseOfTheWeek

March 8 marks International Women’s Day. Today, ICRP celebrates the contributions of women around the world, especially in the field of radiological protection. We look forward to supporting the achievements of all of the incredible women at ICRP over the next year.

When radioactive material enters the body, exposure works a little differently. This week’s Dose of the Week looks at what we call internal dose. #InternalDose #Radiation #ScienceCommunication #DoseOfTheWeek

Join us on 19 March 2026 as members of ICRP Task Group 97 present Publication 159 on Radiological Protection in Surface and Near-Surface Disposal of Solid Radioactive Waste! Everything you need to know and register here: ow.ly/1c6650YkWtv

Radiation dose isn’t just about energy — it’s also about biological effect. This week’s Dose of the Week looks at the unit behind that idea: the sievert. #Sievert #RadiologicalProtection #DoseOfTheWeek #ICRP

February 15th is International Childhood Cancer Awareness Day. ICRP is dedicated to continuing to improve radiological protection to support individuals and families navigating childhood cancer diagnosis and treatment. #InternationalChildhoodCancerAwarenessDay

February 11th is International Day of Women and Girls in Science. ICRP is thankful to have such incredible female scientists who inspire us daily. We cannot wait to see what the future brings for women and girls in science. #InternationaldayofWomenandGirlsinScience

The gray is one of the most common units in radiation protection — and one many people mix up with others. This week’s Dose of the Week clears it up. #Gray #RadiationBasics #DoseOfTheWeek #ICRP

February 4th is #WorldCancerDay. ICRP recognizes the strength and resilience of those who have battled cancer. Through improving radiological protection ICRP is committed to supporting patients and their families through diagnosis and treatment. #WorldCancerDay

The becquerel shows up everywhere in radiation science, but it’s often misunderstood. This week’s Dose of the Week clears it up. #Becquerel #RadiationBasics #DoseOfTheWeek #ICRP
