Radioisotope Decontamination



Radioisotope Decontamination


The management of sites that are suspected to have radioactivity contamination has a three stage management plan; Investigation, Decontamination and Clearance testing. Today, radiation sources are very common;  sensitive smoke detectors (241Am), age determination techniques (14C), sedimentation chronological studies (210Pb), cancer treatments (60Co) to nuclear fission (235U), radioactive particles are almost ubiquitous.


3 step response plan


Initially, historic data on the site is collected to determine the likely nature, scope, location and chemical identity of the risk. An investigation plan and risk assessment is developed, then the site is visited to take initial measurements and sample collection. The samples are then analysed by and independent laboratory for the levels and nature of the contamination.




Based on the site inspection, review of the site history, readings taken at site and laboratory data, a decontamination strategy is developed. This is reviewed with the stake holders, and plans are made to implement the work. Safe work practices are developed and followed and the decontamination proceeds. Any waste produced is appropriately disposed of in appropriate, safe and legal manners.


Clearance testing


A second round of testing proceeds after the decontamination, aimed at confirming the site is clear of hazardous levels of radiation. When that is achieved, final reports of the works are provided with clearance certificates, independent laboratory reports and photographic evidence of the process followed. The aim of this report is to provide appropriate information to subsequent users of the site, that the site is cleared of the identified risks and how that was achieved. Biosafety are an experienced, safe and reliable provider of these complex and highly technical services.
