6th June 2018 – Microanalysis of Particle-Based Uranium, Thorium, and Plutonium in Nuclear Workers’ House Dusts


Seventy-nine dust and 31 soil and sediment samples were collected from the Hanford Nuclear Reservation, Los Alamos National Laboratory, the former Rocky Flats Plant in Colorado, and from homes of workers or abutters of these nuclear facilities.

Activities of individual uranium-, thorium-, or plutonium-bearing dust particles varied by five orders of magnitude, ranging from <0.005 mBq (millibecquerel) to 2,270 mBq. Hanford workplace dusts also had up to 564 ± 24 Bq/kg of137Cs. SEM/EDS techniques reliably detected environmental radioactivity in samples that had barely detectable results by gamma spectrometry. The technique was able to definitively show that thorium, plutonium, and uranium from nuclear facilities could be found in general population settings outside of radiation protection zones.


This should be a serious concern for people who live and work in these areas. This could potentially endanger the health and well being of their entire families, plus this contamination most likely would also be dispersed through the local communities! The uranium, thorium, and plutonium may be in small amounts, but the detrimental health effects would be significantly magnified on ingestion, or if they lodged in the lungs.


2018 – Current radiological situation in areas of Ukraine contaminated by the Chernobyl accident: Part 1. Human dietary exposure to Caesium-137 and possible mitigation measures


This study reports for the first time temporal trends for the period of 2011–2016 in 137Cs content in cow’s milk originating from private farms and households of 14 settlements located in the territories of the Rivne region, Ukraine. These areas are still radioactively contaminated as a result of the accident at the Chernobyl Nuclear Power Plant (ChNPP) in 1986. In 2016, the average 137Cs activity concentration in milk exceeded the Ukrainian Permissible Level (PL) for adults of 100 Bq/l in samples from 6 settlements and the PL for children of 40 Bq/l in 8 settlements, reaching activity concentration of around 500 Bq/l in some samples.

In the absence of governmental programs for implementation of necessary protective measures to reduce radiological risks to impacted populations, the exceedance of PL for the activity concentration of 137Cs in cow’s milk for adults of 100 Bq/l in the Chernobyl-affected areas of Ukraine could persist for many more years – until at least 2040.


Even thirty plus years after the Chernobyl nuclear disaster, the food supply of these communities is still seriously contaminated with nuclear fallout, affecting the health and well being of men, women and children. The 40Bq/l permissible level is still way too high a level for children!

This short animation of Northern and Southern Hemisphere air circulation, shows why we can get detections so far south.

June is winter here in the Southern Hemisphere. The long term June data is showing a gradual increase in winter local background levels,  since the Fukushima Nuclear Catastrophe.
