Home – RadCon

We are expert consultants in the fields of radiation protection, Monte Carlo modelling, radio ecology, retrospective dosimetry, computational dosimetry and data analysis and collection. We perform calculations and measurements for applications in nuclear engineering, physics, and mathematics. We develop software for computations and the assessment and presentation of data. Operating worldwide, we link businesses with research.

RadCon News

RadCon is delighted to be taking part in the 2025 MCNP Symposium this July. RadCon’s Simon Rombauer and Mauritius Hiller will give a short presentation titled “Fission-Matrix Acceleration in Burn-Up Calculations using MCNP6.3” discussing their experience of running burn-up calculations.

Here’s a link to the symposium: https://mcnp.lanl.gov/symposium_2025.html

RadCon’s Mauritius Hiller is presenting a poster on “Transfer of radionuclides from soil to Plants: Database for Radiological Impact Assessments in arid environment” at the ICRER conference in Marseilles, France. The poster will be displayed on Session 6 “Understanding and modelling radionuclide mobility and bioavailability in the environment” on Wednesday, November 27 and Thursday, November 28. The Poster number is P6-31.

It looks at the background of the database on transfer factors in the arid climate zone and gives an outlook on the future development, making the data accessible for researchers.

We’re looking forward to seeing you there and discussing the contents with you.

Monte Carlo Modelling

Monte Carlo Modelling using MCNP, SCALE and PHITS code packages
Advanced Experience in
- Shielding and deep penetration problems
- Air over ground transport problems
- Inventory and burn-up calculations
- Variance Reduction to increase performance of problems

Experience in various applications, including:
- Reactor development: Neutronics, activation, and shielding calculations
- Spent Nuclear Fuel (snf) dry storage cask (dsc) development: Assessment of shielding, inventory, criticality. Load planning. Analysis of interim spent fuel storage installations (ISFSIs)
- Assessment of shielding properties of buildings, nuclear appliances, medical applications

Advanced Reactor Development

RadCon supports the development, manufacture and operation of advanced reactor concepts, specifically Small Modular Reactors (SMRs), with our expertise in neutronics, steady state calculations, and reactor dynamics.

These advanced reactors produce electricity of up to 300 MWe per module and are suitable for use in both single and multiple-unit plants. They can also combine nuclear energy with alternative sources.

The IAEA, which oversees the international nuclear industry, believes the technology has arrived at “an important milestone”, with there now being a global consensus that it has a vital role to play if the goal of net zero carbon emissions is to be reached. The agency has praised the flexibility and affordability that SMRs offer and believes they are a good option for replacing ageing fossil fuel-fired power plants. It highlights their suitability for remote regions with less developed infrastructure and praises their “enhanced safety performance.”

RadCon supports emerging companies with knowledge related specifically to reactors and to physics more generally. We can offer support by providing criticality and burn-up calculations. We also assess fission products and prepare activation inventories, and assist the developers of reactors by helping to calculate and collate all the data necessary for the application process with national authorities.

Database of Radioecological Parameters for Arid Environments

RadCon has developed a Database of Radioecological Parameters for Arid Environments.

It contains information on the development, structure, and application of radioecological parameters, emphasizing their role in supporting predictive modelling, environmental impact assessments, and decision-making during emergencies.

The integration of standardized, region-specific, and quality-assured data enhances the reliability of radiological risk assessments and facilitates rapid response planning.

The main objective of the database is to provide the user with so-called Transfer Factors which indicate the amounts of a radionuclide that is transferred from one compartment to the next within a given time. These compartments include, for example, soil, or parts of plants such as their stem, leaf or fruit.

In total, the database contains:

3300+ Transfer Factor entries;
65 different nuclides from
36 different elements;
data collected in 23 different countries.

The database is constantly updated with new publications emerging, thus allowing users to access up to date values.

For more information, read the following conference abstracts and papers.

The database can be browsed following this link.

Radiation, Environment, Management

RadCon is a Radiation Protection consulting company. It was established in Germany by a small team of professionals with many years of experience in the field of radiation protection, environmental radioactivity, and computational dosimetry.

Drawing on experience built up in different geographical areas, climactic conditions, and ecosystems, RadCon has played a key role in national and international projects supported by the European Commission, The US Department of Energy, IAEA, and other funding bodies.

We are committed to ensuring that future radiation protection projects effectively utilize the knowledge we have built up from these projects, and the lessons that have been learned from them. As part of this we stress our commitment to providing access to reliable and scientifically tested information to help our customers find practical, workable solutions to their problems.

We are ready to share our broad range of knowledge to help and support any organization in need, be it governmental or private.

We cover a broad spectrum of radiation protection services, including:

Risk assessment
Radiation dosimetry: retrospective dosimetry, computational dosimetry, Monte Carlo simulations
Radioecology: Support and development of sampling strategies and measurements; Environmental modelling; Environmental Decision Support Systems (EDSS); Remediation and restoration; Statistical methods and data analysis
Project management
Communication and interaction with stakeholders and the public
German radiation protection ordinance

We operate independently of any state, public, or international organizations. Our expertise is therefore politically impartial and relies solely on experimental scientific data, which means there is no risk of any conflicts of interest.

Radio Ecology

Radioecology is the study of the effects of radiation and radioactive substances on ecological communities. It is a highly multidisciplinary scientific field which looks at environmental radioactivity, whether natural or man-made, and its effects on people and the natural environment. It deals with radioactivity as a stressor requiring risk assessment, but also as a tracer of biogeochemical and ecological processes.
