1. Development of Radon Detectors for Earthquake Prediction
University essay from KTH/Skolan för teknikvetenskap (SCI)Abstract : The purpose of this project is to simulate the detection of γ-ray spectra emitted by radon isotopes and their daughters. This is done as a contribution to the development of radiation detectors to be used in a research project investigating the possibility of using increased amounts of the radioactive gas radon as an earthquake precursor.

3. Accumulation of 63Ni, 106Ru and 125Sb in phytoplankton
University essay fromAbstract : Background: Nuclear Power Plants (NPPs) release small amounts of radionuclides which contribute with a low radiation dose to the environment as well as humans and animals. In this context, marine ecosystems are critical, since most NPPs in Sweden are located by the sea. READ MORE

4. Evaluation of whole-body bone scans performed using a gamma camera with Cadmium Zinc Telluride detector
University essay fromAbstract : The bone scan is a common nuclear medicine imaging procedure that is mainly used for evaluating several oncological patient groups. A radioactive tracer, 99mTc -labelled diphosphonate, is injected intravenously and accumulates in the skeleton. The distribution of the tracer in the body is measured with a gamma camera 3 hours post-injection. READ MORE
