The radionuclides-laboratory at the NIOZ-Texel is a lab where under the supervision of the radiation experts Level 3 experiments can be performed with radioactive isotopes. Only employees who successfully complete a radiation safety course (minimum level 5b) are allowed to carry out their work. The radionuclides-laboratory of NIOZ is located in building E00-21, is part of the Department of Biological Oceanography and accessible to employees on work days from 08: 00 – 17: 00. For working outside these times you need to consult with the responsible radiation expert.

NIOZ-Texel has a license for the C-lab for the holding and applying open sources within the location to a maximun of 3 radio toxicity equivalent for inhalation (Re_(ing)). The license permit work with ³H, ¹⁴C, ³²P, ³³P, ³⁵S en ⁴⁵Ca. Currently (January 2012) are only ³H Leucine , ¹⁴C Sodium bicarbonate used.

NIOZ-Texel also has a licence for possession and apply of open sources aboard of research vessel to a maximum of 2.2 radio toxicity equivalent for inhalation (Re(ing)). For this purpose there are 2 containers as  fully C-lab furnished. During sailing trips where radionuclides are used, always 1 radiation expert level 3 has to be on board. Since there are stringent legal requirements for working with radionuclides, they should be applied only in the isotope laboratory. All operations with radionuclides have to be done inside the fumes.

From 1 January 2012 on you will be billed at € 2 per measured sample. With this contribution, all users are covered for the disposal of radioactive waste, the use of scintillation cocktails, gloves, pipette tips, and further lab facilities. The user must, in consultation with the radiation experts themselves acquire the radionuclides.

Working-instruction radionuclides in the C- laboratory

1. The C-lab may only be entered by the persons which are authorized and registrated before the experiments by the radiation-officer.
2. In the C-lab only radiological work may be performed that is described in a protocol and approved by the radiation-officer.
3. Before and after the normal working hours it is not allowed to work in the C-lab without permission of the radiation-officer.
4. It is forbidden to eat, drink, smoke or use cosmetics in the C-lab.
5. Using a lab-coat is obligatory. This may only be used in the C-lab for working with open radioactive isotopes.
6. Use while working with a higher risk for contamination always gloves.
7. After each experiment the working site has to be controlled for radioactive contamination. Once a month a big control of the work area is done by Kirsten Kooiman.
8. Each contamination has to be cleaned and removed by the person that caused it.
9. The radioactive waste has to be dumped in the for that purpose available waste bins.
10.   Radioactive material may only be brought outside the C-lab with permission of the radiation officer.
11. Radioactive contaminated glassware and other things may not leave the C-lab. It has to be cleaned in the C-lab or be treated as radioactive waste.
12. Before leaving the C-lab you have to wash the hands and check the hands and clothes for radioactive contamination.

Instructions for accidents:

1. A radioactive contamination has to be cleaned by the person that caused it and the radiation-officer has to be informed.
2. After the cleaning the nearby surroundings of the radioactive contamination has to be checked for remaining radioactive contamination.
3. In case of the radioactive contamination of a person, the radiation- officer has to be informed immediately, tel. 0222 369 500 or 06 5733 1350. The precautions for more contaminations and the decontamination of the person will be instructed by the radiation-officer.
4. Inform the radiation-officer if you see anything in the C-lab that in your opinion is not correct concerning the radiation hygiene.
5. In case of fire or other calamities call 112, or reception 9 and warn the radiation-officer.

Bij het NIOZ Koninklijk Nederlands Instituut voor Zeeonderzoek zal in de herfst van 2012 een zeewier-testcentrum in gebruik worden genomen. Het maakt deel uit van het 'Netherlands Seaweeds Science and Technology Center (SSTC)' dat zich ten doel heeft gesteld om het fundamentele onderzoek aan zeewier en de grootschalige productie van zeewier samen te brengen. Het zeewieronderzoek zal op verschillende schalen plaatsvinden, van kleinschalig laboratoriumonderzoek tot grootschalige studies in tanks en op open zee (b.v. de zeewier-boerderij op de Noordzee). Het SSTC bestaat uit het NIOZ Onderzoeksinstituut, de zeewier-testfaciliteit en de NIOZ-kennishaven. Samenwerkende partners zijn Hortimare, ECN, IMARES, EcoFys & PRI Wageningen.

De testfaciliteit kan worden gebruikt voor ecofysiologische studies waarbij het effect van omgevingsvariabelen (temperatuur, licht, voedingsstoffen, zoutgehalte) op de groeisnelheid en -opbrengst van het wier worden getest. 

Het ontwerp is modulair, dwz iedere tank kan worden vervangen door een kleinere of grotere variant en de tanks zijn afgesloten met een deksel. Schoon zeewater wordt aangevoerd vanuit het nabijgelegen Marsdiep en afvalwater wordt via Ulva lactuca filters weer geloosd.

Lokale zeewiersoorten zoals Laminaria digitata, Daccharina latissima, Palmaria palmata en Ulva lactuca kunnen worden getest.
