One Radiatin Safety Recrds binder will be issued by EHS fr each rm that is permitted t stre r use radiactive materials. Nrmally, ne binder shall be issued per rm regardless f the number f permits n the rm. Recrds required t be in the lab: Leak test and sampling certificates Radiactive Surce Inventry Lg Frm (green sheets r cpies f the green sheet n white paper fr items that have been dispsed)(effective January 1, 2018) Cpies f TDG certificates (receiving class 7 Radiactives) fr lab persnnel All in lab site specific training related t Radiatin Safety, such as: Safe Wrk Prcedures listed as a cnditin n the Internal Radiistpe Permit A cpy f the Lab Assignment (effective September 14, 2016) Cpies f any incidents, malfunctins, security breaches related t Sealed Surces and Radiatin Devices (listed n the Permit). Keep all recrds fr a minimum f 8 years and d nt discard until authrized by EHS (at time f annual inspectin). 6. Ordering/ Obtaining Radiistpes and Inventry (Frms) The University is licensed by the Canadian Nuclear Safety Cmmissin t use specified item limits f Sealed Surces and specific Radiatin Devices. T ensure the University des nt exceed the, Page 4 f 12
licence limits, all rders and transfers t and frm the University must be pre-apprved by Envirnmental Health and Safety. 6.1 Envirnmental Health and Safety Respnsibilities related t Ordering Sealed Surces Envirnmental Health and Safety (EHS) is respnsible t pre-apprve every transfer r rder f radiactive material. EHS will: Prvide radiatin safety pre-apprval f every transfer r rder f radiactive material. The pre-apprval prcess will ensure the University is licensed t receive the rder. An assessment is made t ensure the pssessin, use and strage f this item in the permitted facility will cntrl radiatin dse ensuring ALARA. Effective January 1, 2018, EHS will generate a unique Radiactive Surce Inventry Lg Frm (Inventry Lg Frm) n green paper fr every radiactive Sealed Surce r Radiatin Device based n infrmatin frm the transfer r purchase request. By April 1, 2018, EHS will prepare an Inventry Lg Frm fr Sealed Surces and Radiatin Devices received prir t January 1, 2018. EHS maintains an inventry f all scintillatin cunters, gamma cunters, radiatin survey and cntaminatin meters. 6.2 The Permit Hlder Respnsibilities related t Ordering Sealed Surces The Permit Hlder is respnsible t ensure: Every transfer r purchase f radiactive material has radiatin safety pre-apprval frm EHS. Orders are placed nly fr radiistpes listed as apprved n the current Internal Radiistpe Permit and the apprved item limits are nt exceeded. (If the radiistpe is nt listed n the Permit r the rder is greater than the surce activity n the Permit, the Permit will need t be amended prir t placing the rder.) Effective April 1, 2018, every Sealed Surce r Radiatin Device in the pssessin f the lab has its wn unique Radiactive Surce Inventry Lg Frm as generated by EHS. Radiactive Surce Inventry Lg Frms are kept in the Radiatin Safety Recrds binder in the rm where the Sealed Surce r Radiatin Device is nrmally lcated. Recrds are up-t date and readily available fr inspectin. When a surce decays belw ne exemptin quantity (EQ), it shuld be remved frm the Permit, and this actin nted n the Inventry Lg Frm. The riginal n green clred paper, is kept in the lab until the Sealed Surce r Radiatin Device is transferred t EHS fr dispsal. All permitted Sealed Surces and Radiatin Devices are stred in a safe and secure manner. Sealed Surces that are nt in use are stred in a lcked cupbard r lck bx t ensure they are nly accessible t Permit Hlders r Designated Wrkers. EHS is immediately infrmed f any Sealed Surce r Radiatin Device that des nt have a unique EHS generated Radiactive Surce Inventry Lg Frm. The required infrmatin is accurately recrded n the Radiactive Surce Inventry Lg Frm. Discrepancies between the riginal rder infrmatin and the item as received are recrded in the space prvided n the Inventry Lg Frm. Significant discrepancies (>10%) shuld be prmptly reprted t EHS. The Serial Number f the Radiactive Surce Inventry Lg Frm is cpied nt the crrespnding Sealed Surce (r equivalently the cntainer, baggie r tag assciated with the Sealed Surce) r labelled nt the Radiatin Device. The Radiactive Surce Inventry Lg Frm may be used t recrd the use f the item r dcument hw / where these recrds are kept. Fr example, if the use lg f a Radiatin, Page 5 f 12
Device (eg Liquid Scintillatin Cunter) is cmputerized r kept in a separate dcument, then this is clearly described n the Radiactive Surce Inventry Lg Frm. Uses wuld include security checks (further described belw), leak tests, installatin f a Sealed Surce int a device, transferring a surce r device t anther permitted r licensed lcatin, returning surces t strage, and ultimately, transferring Sealed Surces r Radiatin Devices t EHS fr dispsal. Fr Sealed Surces and Radiatin devices cntaining mre than 50 megabecquerels (50 MBq), a lg is kept f the date, the name f the persn that uses r handles the Sealed Surce r Radiatin Device and the manner the Sealed Surce r Radiatin Device was used. Effective January 1, 2018, the nly accepted methd f dispsal fr Sealed Surces r Radiatin Devices is t transfer t EHS alng with the crrespnding Radiactive Surce Inventry Lg Frm. A cpy n white paper f the Radiactive Surce Inventry Lg Frm is kept in the Radiatin Safety Recrds Binder (fr 8 years past the discard date). All Sealed Surces and Radiatin Devices listed n a Permit are physically inventried at least nce per calendar year and this security check is recrded n the crrespnding Radiactive Surce Inventry Lg Frm. Physically verifying inventry mre ften (fr Categry 4 and Categry 5 Sealed Surces) as prescribed by CNSC) and any ther security requirements as specified in the Permit cnditins. All transfers f Sealed Surces r Radiatin Devices within the University are recrded n the Inventry Lg Frm including the date and the Permit Number f the receiving Permit. All mvement f Sealed Surces r Radiatin Devices t and frm the University is crdinated in advance with EHS. EHS is infrmed f all scintillatin cunters, gamma cunters, radiatin survey and cntaminatin meters in the Permit Hlder s department whether they are in use r nt. EHS shuld be infrmed f newly acquired equipment as well as equipment that is leaving the department. EHS will assist in making the prper arrangements t discard r transprt. Orders fr Sealed Surces r Radiatin Devices are placed using the University e-prcurement system. The current e-prcurement prcedure is available n the EHS web page. If the e- prcurement prcedure cannt be fllwed (i.e. Radiatin Devices may have purchasing requirements r cntrls that supersede e-prcurement), cntact EHS (radsafe@umanitba.ca) t ensure radiatin safety pre-apprval frm EHS PRIOR t placing the rder! 7.
