A memento given to Julian Bayley by the Mechanical Maintenance group at the Darlington Generating Station marking his 35 years of service with Ontario Hydro. It consists of a 10 cm tall stainless steel flask, with a “stopper”, mounted on a 26.5 cm by 17 cm wooden base. The “flask” is a replica of a standard, plastic, disposable, urine-sample bottle used by all Atomic Research Workers (ARWs) who might have been exposed to tritiated heavy water after maintenance work, or even to submit monthly as required for all ARWs regardless of work performed.
The tops were sized like an old-style glass milk bottles and used similar paper lids with finger grabs used in such milk bottles. The flasks were routinely used for urinalysis for other bioactive radiological agents such as Carbon 14 (occurring in the annulus gas surrounding the calandria tubes), or from airborne/waterborne radioiodines from fuel failures. Analysis was done simultaneously.
