  2. 11. Tools for the Advancement of Radiopharmaceutical Therapy

    Author : Emma Mellhammar; Forskningsgruppen för Systemisk strålterapi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiopharmaceutical therapy; Nuclear medicine; Monte Carlo simulation; Intratherapeutic preclinical PET; Alpha particles; Beta Particles; radionuclides; Radiobiology; γ-H2AX; Dosimetry;

    Abstract : Radiopharmaceutical therapy is used to treat cancers and other diseases with radiolabeled pharmaceuticals. The treatment targets specific cells, and the emitted ionizing radiation cause cytotoxic damage. Dosimetry is performed to estimate the absorbed dose from the energy deposited in the body. READ MORE

  4. 12. Risk from radionuclides: a frog's perspective : Accumulation of 137Cs in a riparian wetland, radiation doses, and effects on frogs and toads after low-dose rate exposure

    Author : Karolina Stark; Nils Kautsky; Petra Wallberg; Torbjörn Nylén; Michael Gilek; Dennis Woodhead; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dose model; mass balance budget; overbank sedimentation; amphibian; phantom; thermoluminescence chip; radiosensitivity; DNA damage; Biology; Biologi;

    Abstract : Threats from man-made radionuclides include waste issues, increasing number of power plants, underground bomb testing, nuclear weapons, and “dirty bombs”. Until recently the ionizing radiation protection system focused on protecting humans with an implied protection of biota. READ MORE

  5. 13. Diffusion of Radionuclides in Bentonite Clay : Laboratory and in sity Studies

    Author : Mats Jansson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bentonite; montmorillonite; cation; anion; diffusion; sorption; cobalt; caesium; strontium; iodide; pertechnetate; surface diffusion; in situ; Chemistry; Kemi;

    Abstract : This thesis deals with the diffusion of ions in compactedbentonite clay. Laboratory experiments were performed toexamine in detail different processes that affect thediffusion. To demonstrate that the results obtained from thelaboratory investigations are valid under in situ conditions,two different kinds of in situ experiments were performed. READ MORE

    Author : Synnöve Sundell-Bergman; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : .... READ MORE

  7. 15. Extreme solar particle storms and links to solar activity inferred from cosmogenic radionuclides in ice cores

    Author : Chiara Paleari; MERGE: ModElling the Regional and Global Earth system; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ice cores; cosmogenic radionuclides; Solar storms; 10Be; 36Cl; Solar energetic particles;

    Abstract : During solar storms, large amounts of solar energetic particles (SEP) are accelerated into the interplanetary medium and sometimes hit Earth. These events, known as SEP events, can have harmful impacts on our modern society by affecting spacecrafts and potentially astronauts in space. READ MORE
