Qualification Details

To be qualified to take employment as postdoc, you must have been awarded a doctoral degree or have a foreign degree that is deemed to be equivalent to a doctoral degree.  This degree must have been awarded at the latest by the point at which LiU makes its decision to employ you.

It is considered advantageous if your doctoral degree is no older than three years at application deadline for this job. If there are special reasons for having an older doctoral degree – such as taking statutory leave – then these may be taken into consideration.

We are looking for a candidate with a PhD in advanced gamma spectrometry, nuclear physics, computer science or machine learning. Experience with developing neural networks is expected. Experience with gamma ray spectrometry and emergency preparedness would be advantageous. We expect that you can work independently, that you are curious and have good collaborative skills, as the project is performed in collaboration with specialists in gamma spectrometry and the radiation protection authority (SSM). The language used within the project is English. The research group is international, therefore it’s important that you have communication skills in English.

Responsibilities/Job Description

Work assignments

As postdoc, you will principally carry out research. A certain amount of teaching may be part of your duties, up to a maximum of 20% of working hours.

Radiation emergencies occur infrequently, but when they do occur, they may affect a large fraction of the population. In such situations, fast response on radiation protection measures must be provided by the governmental authorities, like the Swedish radiation safety authority (SSM). One of the key input parameters for radiation protection measures is the radionuclide composition in the released material to the environment.

The postdoc project aims to develop artificial neural networks (ANNs) to identify and quantify radionuclides in gamma-ray spectroscopy (HPGe detectors) quickly and accurately. The trained ANN systems will mimic the expertise and experience of the spectroscopist. The ANN will use gamma ray spectra computed via Monte Carlo simulations of the HPGe detector response as training and validation data. Spectra measured by the device and spectra available in the literature will be used for the testing of the proposed neural network. Such an AI system would be an essential tool in radiological emergencies and provide the expert and the SSM with qualified estimates on the released radioactive material. In the future, such systems could be further developed in many other applications, e.g. field gamma spectroscopy, where in addition to identification, also determine the depth distribution of the radioactive material in the soils.

The project will be supported by the radiation physics group, the machine learning and artificial intelligence competence in LiU.

The workplace

You will work at the Department of Health, Medicine and Caring Sciences (health physics group), a department where many interesting projects are ongoing. You will have access to gamma spectrometry and state-of-the-art-hardware for deep learning, within the research group but also through Sweden National Supercomputer Center (NSC) at Linköping University.
