“…The 241 Pu/ 239+240 Pu activity ratio in the air dust samples increased from 34 (March 1986) to 56 (April 1986) after the accident and decreased slowly reaching 36 (December 1986) (Strumińska and Skwarzec 2006 ). Similar situations were observed in Vienna and Salzburg (Austria), Belgrade (Serbia), and Vilnius (Lithuania) (Irlweck and Wicke 1998 ; Vukanac et al 2006 ; Lujaniene et al 2009 ). Mietelski et al ( 1999 ) suggested that the initial (at the moment of the Chernobyl accident) deposition of 241 Pu in Poland might have been relatively high, up to the level of 2 kBq m −2 .…”

The paper presents unique data of plutonium 241Pu study in seabirds from northern Eurasia, permanently or temporally living at the southern Baltic Sea coast. Together, ten marine birds species were examined, as follows: three species that permanently reside at the southern Baltic, four species of wintering birds, and three species of migrating birds; 366 samples were analyzed. The obtained results indicated plutonium was non-uniformly distributed in organs and tissues of analyzed seabirds. The highest 241Pu content was found in the digestion organs and feathers, the lowest in muscles. Also, the internal radiation doses from 241Pu were evaluated.

“…It is possible to assess the 241 Pu emission by the April 2020 wildfires using the original 241 Pu/ 239+240 Pu activity ratio and applying a simple 241 Pu decay. This ratio was estimated for May 1986 in a range between 70 and 100. ,− or even in a range of 82 to 120 in upper parts of lichens, 98 in air filter (May 1, 1986), and 95 in grass (May 1, 1986) . Considering a global average ratio of 100 at the time of the accident and neglecting 239 Pu and 240 Pu decays as of April 2020, the 241 Pu/ 239+240 Pu activity ratio would have been about 19.1 during the wildfire event.…”

From early April 2020, wildfires raged in the highly contaminated areas around the Chernobyl nuclear power plant (CNPP), Ukraine. For about 4 weeks, the fires spread around and into the Chernobyl exclusion zone (CEZ) and came within a few kilometers of both the CNPP and radioactive waste storage facilities. Wildfires occurred on several occasions throughout the month of April. They were extinguished, but weather conditions and the spread of fires by airborne embers and smoldering fires led to new fires starting at different locations of the CEZ. The forest fires were only completely under control at the beginning of May, thanks to the tireless and incessant work of the firefighters and a period of sustained precipitation. In total, 0.7−1.2 TBq 137 Cs were released into the atmosphere. Smoke plumes partly spread south and west and contributed to the detection of airborne 137 Cs over the Ukrainian territory and as far away as Western Europe. The increase in airborne 137 Cs ranged from several hundred μBq•m −3 in northern Ukraine to trace levels of a few μBq•m −3 or even within the usual background level in other European countries. Dispersion modeling determined the plume arrival time and was helpful in the assessment of the possible increase in airborne 137 Cs concentrations in Europe. Detections of airborne 90 Sr (emission estimate 345−612 GBq) and Pu (up to 75 GBq, mostly 241 Pu) were reported from the CEZ. Americium-241 represented only 1.4% of the total source term corresponding to the studied anthropogenic radionuclides but would have contributed up to 80% of the inhalation dose.
