3.0 DETAILS OF RADIOACTIVE CONTENT

Principal Radionuclide Caesium-137

Half life 30.17 years

Principal emission 662keV gamma photons.

Radionuclidic Purity Cs-134 less than 1.0% of Cs-137 by activity.

Aggregate of other radionuclidic impurities less than

2% of Cs-137 by activity.

Active Form Anhydrous caesium chloride as compacted powder.

Activity distribution The caesium chloride compact completely fills the

inner capsule of a source. The activity is distributed

evenly through the compact as far as is reasonably

practicable but REVISS makes no specification or

guarantee of either axial or radial uniformity.

Activity Content Minimum, Nominal and Maximum content activities

are included in Appendix A.

On request and by agreement confirmed in writing a

source may be supplied with a content activity below

the minimum level relevant to its type as stated in

Appendix A. Where content activities less than the

minimum levels quoted in Appendix A are required

they will be achieved by addition of inactive CsCl to

the active material in a uniform mix.

RADIOACTIVE SOURCE IMPORT CERN SPECIFICATION N°4541RP-20120803-AE FOR QUOTATION REQUEST

This note describes CERN requirements to order the following radioactive source. If any one of the conditions is not fulfilled, CERN reserves the right to send back the source.

1. SOURCE SPECIFICATION

- All sources bought by CERN must be sealed according to ISO2919(1) standard. - Isotope: 137Cs - Emission wished: Gamma - Purpose: Source for a gamma irradiation facility. - Expected activity: 16.6 TBq on 01/09/2013 - Expected uncertainty: +/- 20 % - Source shape expected As small as possible - Conditions for use 20°C, 1 bar - Sealed sources used in gamma irradiation facilities shall meet the general requirements of

sealed sources given in ISO Standard 2919 according to the category of irradiator.

- RWL* expected ≥ 10 years - General conditions: Source must have a serial number which will have to be engraved

on the source itself (with a radioactive sign and the isotope, if possible). This information must be displayed on all source holders as well as included in the certificates (cf.: section 4).

2. ADDITIONAL TESTS:

The source will also have to be resistant to corrosion. Tests shall be performed according to ISO7384 (Corrosion tests in artificial atmosphere) or equivalent on one or several dummy capsules.

3. ISO9978 TESTS:

After the required ISO2919 tests and the specific tests described above, the source will have to be checked for radioactive leakage in compliance with ISO99782. Please find below references for the tests that CERN expects but note that these are only suggestions. It remains the responsibility of the suppliers to define the suitable method(s) which does not damage the source. If, in fact, one of the suggested methods cannot be used, suppliers should clarify and justify it within the quotation.

- Immersion (ISO 9978 § 5.1).

1 International standard ISO2919 – « Radiation protection — Sealed radioactive sources — General requirements and classification » – 1999. 2 International standard ISO9978 – « Radiation protection — Sealed radioactive sources — Leakage test methods » – 1992. *RWL: Recommended Working Life of the source, i.e. the time during which the source shall remain usable and sealed (according to ISO2919°), in thenormal condition for use(described in §.1).

4. CERTIFICATE PAPERS

A certificate will have to be provided with the following information included:- the isotope: which should also be engraved on the source - the activity: with its date and uncertainty, - the impurity(ies) (if relevant)- the serial number: which should be engraved on the source - the product code,- the drawing number: with a technical drawing enclosed, - ISO2919 certification: i.e. a statement of the corresponding classification. - the Recommended Working Life- the leakage measurements: description of the leakage measurement with procedures,

results, detectors, minimum detectable activity… - the specific tests carried out: description of the tests specifying times, temperature,

pressure… - the supplier: name and details, - a repossessing commitment: describing the conditions of the supplier repossession. - all specific safety instructions related to the source will have to be detailed within the

certificate.

If the “normal/standard” certificate is not sufficient to fulfill all of these above requirements, could you please use the following form: https://edms.cern.ch/file/735208/LAST_RELEASED/RadSource-Certificate.pdf https://edms.cern.ch/file/735208/LAST_RELEASED/RadSource-Certificate.doc

The original certificate must be sent with the source parcel. In addition, we would like to receive an electronic version by email as soon as possible (i.e. before shipment).

5. PACKAGING AND TRANSPORT

Dispatching to CERN can start only after receiving the importation agreement from CERNRadioactive Shipping Service.

The source will have to be shipped to CERN’s goods reception on Meyrin (DDU Meyrin) under supplier responsibility according to dangerous goods international regulations.

In addition, please note that the following requirements for import of radioactive material to CERN must be followed: http://cern.ch/service-rp-shipping/#Import

The package and/ or the irradiator shall be appropriately locked in order to avoid any access to the source, the inner part of the package and/ or the irradiator shall be marked with the ISO 21482 radiation sign (given in Annexe 1)
