Selected Neutron Image of the Month

January 2021

Fig. 8. NCT-rendered images of pristine (room temperature) and pyrolyzed (1000 °C) samples: (a) axial and (b) radial throughcuts of the samples defined in Table 2 and shown in Fig. 9.

December 2020 Neutron Image of the Month


Figure 4.

(a) The horizontal cut through the tomography image of the partially dried sample (after 11.5 h of drying) reveals the dry zones. The light-gray regions contain water and maltodextrin (it is noted that maltodextrin and heavy water are not distinguished from this image).

(b) Schematic illustration of the different zones that are distinguished from the tomography image. The red arrows depict the expansion direction of the dry zones.

1: accumulation of maltodextrin inside the peripheral maltodextrin belt;

2: peripheral sublimation zone with fractal front;

3: ring of frozen water and maltodextrin;

4: sublimation fingering zone.

Conference and other news





Congratulations to Marios and SCITEK Consultants Ltd  who moved into their new offices in Victory Road, Derby, U.K. on the 10th December 2020.

SCITEK designed, built and installed the Cold Neutron Radiography Facility on the China Mianyang Research Reactor (CMRR) in Sichuan, China.

In addition, they provide advanced engineering services to clients in a variety of sectors including aerospace, defence, power generation and automotive and carry out collaborative R & D programmes with academic and industrial partners.

For more information:-

The IAEA has announced the launch of a new 

Neutron Imaging E-Learning Course with registration being made via the IAEA Portal NUCLEUS. 

Frikkie de Beer has announced his early

retirement from Necsa, Pretoria. In his

32 years at Necsa, he created and made

operational a microfocus X-ray CT facility

that complemented the NRAD facility on

the South African SAFARI-1 reactor that is currently in the process of being upgraded to maintain these facilities as one of the major laboratories in the field of nuclear NDT studies.  He has been involved in many international projects at laboratories around the world and been instrumental in furthering the use of neutron techniques in NDT with students and professional users in South African industry and academia. He has been president of the International Society of Neutron Radiography and hosted the highly successful World Conference on Neutron Radiography WCNR-9 at the Kwa-Maritane, Pilansberg National Park in 2010. We wish him good health and success in his new projects.

News from Argentina that due to the deteriorating COVID-19 situation, the 6th ITMNR meeting in Buenos Aires has been postponed.

The 1st International Conference and School on Radiation Imaging (ICSRI-2020), scheduled for November 22-26, 2020 at Ferhat Abbas University, Setif, Algeria has been postponed.

After 40 years of successful neutron research in Berlin-Wannsee, the research reactor BER II was finally shut down at the end of 2019. It will be dismantled over the next two decades.

The WCNR-11 conference in Sydney was a big success and the proceedings have become available at
For more details of the meeting plus other developments in the Neutron Imaging field visit the INSR website
Details of the WCNR-11 programme with PowerPoint files of many of the presentations are at
The 12th WCNR will be held at the Idaho National Laboratory in 2022 and Aaron Craft has been elected as the new ISNR President.
The 20th World Conference on Non-Destructive Testing (WCNDT) will be in Incheon, Korea, May 31-June 4, 2021.

The latest ISNR newsletter is at: 

 1964 - 1977

Newly published by the ASNT: The Nondestructive Testing Handbook, Fourth Edition: Volume 3, Radiographic Testing RT) offers revised and expanded content throughout, including over 150 new color images contributed by practitioners around the world. A chapter on neutron radiography has been added, as well as new technical information in the areas of digital imaging, data processing, and digital image reconstruction
