Radiotoxological monitoring - UKHSA holds UKAS accreditation for analysis of isotopes of plutonium, americium and uranium in urine and faeces.
The fatal poisoning of Mr Alexander Litvinenko by polonium-210 was an extraordinary event presenting unique public health challenges. UKHSA were tasked to establish the extent of contamination and the broader threat the radioactive contamination represented.
In response, UKHSA rapidly initiated an extensive sampling monitoring programme to identify those potentially exposed.
At each location, risk assessments were undertaken to identify and assess all those who may have been exposed to radioactive contamination. Direct exposure assessment also informed decisions regarding the need for further sampling and was instrumental in providing reassurance for all directly concerned and the broader community at large.
Urine samples from 753 people were processed: about 500 during the first month, another 250 up to the end of May 2007, and a further three up to August 2007.

Through this time over 1200 urine samples and 150 faeces samples were analysed for a mix of U-234; U-235; U-238; Pu-238 and Pu-239+240 and Am-241. These samples originated from outside the UK and as such required transportation in compliance with European packaging and transportation legislation as well as time sensitive delivery under temperature controlled conditions.
UKHSA's experience in the complex logistics and Health and Safety implications associated with transporting this type of sample ensured the monitoring programme was completed to the highest quality and analysis standards.
