Polonium

Polonium (Po) — 10-Year Trends

As of 2026-09-11 · the last 10 years

Polonium’s research intensity currently sits at about 13% of its all-time peak, a level that has remained essentially flat over the last decade.

Research intensity ran from about 14% of the element's own all-time peak in 2016 to about 13% in 2026 — essentially flat across the window, and the all-time peak (1954) lies before this window. Over the same span its share of research attention across all elements held steady. Among the 118 elements, polonium has a mid-sized research literature.

The number of papers involving the element rose from about 288 in 2016 to about 522 in 2025 (1.81x). That is slower than the literature as a whole grew over the same years, so the element lost ground in the wider body of research even as its own count rose.

The dominant research community is Polonium-210 Production and Environmental Dose Assessment, which accounts for about 55% of the element's recent research. This work focuses on the nuclear production of polonium-210 and the assessment of radiation doses from environmental and drinking water exposure, with distinctive attention to naturally occurring isotopes and dose assessment. Polonium is a minor presence in this much larger community, appearing in only about 3% of its papers. The community’s share has remained steady over the window. A key anchor is the 2017 ICRP Publication 137 on occupational intakes of radionuclides, cited over 370 times, alongside a 2025 study on radon and polonium concentrations in rocks, cited about 16 times.

A second significant area is Polonium Isotope Half-Lives and Shape Coexistence, holding about 10% of recent research. These papers measure the half-lives of polonium isotopes and investigate nuclear shape coexistence, distinct from the broader community's focus on superheavy element synthesis. Polonium is a minor presence here as well, involved in about 2% of the community's papers. The share is steady, though it has slightly declined from 12% in the previous period. Notable work includes a 2019 Physical Review Letters paper on incomplete fusion products, cited about 55 times, and a 2025 study revealing the nature of yrast states in neutron-rich polonium isotopes, cited about 3 times.

Advanced Nuclear Reactor Materials and Corrosion Science constitutes about 9% of the element's recent research. While the specific role summary is not detailed, the community involves polonium as a minor presence, with under 1% of its papers involving the element. The share has remained steady, showing a slight increase from 6% in the earlier period. A relevant 2025 Surface Science paper analyzes the capture of volatile polonium-210 in lead-bismuth eutectic coolant environments, cited about 3 times.

Overall, the composition of polonium research has been stable, with the environmental dose assessment community maintaining its dominant share while nuclear physics and reactor materials communities hold steady secondary positions. The remainder of the research, comprising about 26% of the literature, is distributed across other smaller communities.
