For DD to receive multiple pieces of radioactive waste, we require a range of information concerning the waste before the transfer can take place.

This information must be entered into the DD Excel sheet, which can be downloaded from the menu on the right. Subsequently, the completed Excel sheet must be uploaded to DD in the window below.

Further down the page, a guide for completing the DD Excel sheet can be found.

Please note that a submitted DD Excel sheet cannot be edited on this page; modifications can only be made by contacting a DD employee.

Guide to the declaration of radioactive waste to DD.

Fields marked with * must be completed

Declaration ID (cell E1):

To be completed by DD. The declaration will receive a unique case number, which DD will be able to refer to.

*Company name/customer (cell E2):

Briefly specify the waste notifier. DD possesses the contact information from the profile.

*A: Source ID/Serial No.:

Sources frequently possess a unique identification number, typically located on a source plate and/or its corresponding certificate. Low-activity sources may not have an inscribed ID but will have an associated certificate.

*B: Waste Type:

From the drop-down menu in the cell, select the waste type that most accurately describes the item:

Combustible / Smoke Detector / School Source / Apparatus / Solid Waste / Organic Liquid / Inorganic Liquid /

Source / DEFECTIVE Source / Biological Waste / OTHER (specify under remarks, point O)

*C: Identification of Waste Item for DD Handling:

It is crucial that each individual waste item is readily identifiable with the necessary source information, particularly when multiple sources are transferred concurrently. Please clearly inscribe or mark the specified identification number on the waste item. If several sources are packaged within the same container, specify the contents of that container. For example, Box A contains sources 1, 4, and 5; Box B contains sources 2, 3, and 6.

D: Application Details: Information on the Source's Use:

Kindly provide a brief description of the source's application, e.g., density gauge, source extracted from an apparatus, organic chemistry from experiments, etc. This information assists DD in gaining a clearer understanding of the source.

*E: Source Nuclide (Isotope) Information:

Specify the nuclide (isotope). The most common isotopes can be selected from the drop-down list, e.g., I-125, H-3, C-14, Fe-55, Co-60, Am-241, etc. If the isotope is not listed, please manually enter it (note that the spreadsheet will not be able to calculate decay in this case).

*F: Physical State (Liquid/Solid)? Sealed/Unsealed Source:

DD requires knowledge of the source's physical state and whether it is a sealed or unsealed source, which is critical for handling upon receipt and subsequent processing.

*G: Reference Activity:

Provide the source's reference activity, which can be found on the 'source plate' or its accompanying certificate. In conjunction with the reference date, the current activity can be calculated.

*H: Unit of Reference Activity:

From the drop-down menu in the cell, select the unit for the specified reference activity:

GBq / MBq / kBq (Conversion of old unit: 1 mCi = 37 MBq)

*I: Reference Date (dd-mm-yyyy):

State the date of the reference activity. This enables the calculation of the current activity.

J: Half-life [days] (locked):

The half-life in days for the listed isotope (column E) is automatically retrieved. This value is utilized for decay calculations.

 K: CURRENT (calculated) activity after decay [MBq] (locked):

Calculation based on reference activity, date, and isotope (half-life).

 L: Unit of current activity (locked):

Same as column H.

 M: Date of calculated CURRENT activity (dd-mm-yyyy) (locked):

Retrieves current date.

*N: Shielding:

Please describe the source's shielding or packaging. It is important to know the type of shielding behind which the dose rate was measured. This information can provide DD with a better understanding of the source.

*O: Measured dose rate on the surface of the source [µSv/h]:

The dose rate is measured on the surface of the source at a maximum distance of 1 cm. Liquid sources are measured on the surface of the container. Determine the maximum value. This information is crucial for radiation safety during the handling of the source upon DD receipt (as well as for transport and ADS regulations).

P: Measured dose rate 1 meter from the source [µSv/h]:

This can serve as a valuable check of the dose rate measured on the surface and provide DD with a better understanding of the source and its handling upon receipt.

*Q: Weight [kg]

This can provide DD with a better understanding of the source and its handling upon receipt. Sources are also weighed at DD for invoicing purposes.

*R: Volume [L]

This can provide DD with a better understanding of the source and its handling upon receipt. This is also relevant for invoicing purposes.

S: PHOTO?

Is a picture of the waste item attached to the notification, Yes/No (drop-down list).

T: Other relevant remarks:

Any information regarding DEFECTS, or anything unknown about the waste item.

Please upload pictures of all waste items, their certificates, inspection reports, or other relevant information about the source.
