Radiochromic Film Dosimetry in Kilovoltage X-­‐ray Beams: A Pre-­‐ Investigation for In Vitro Studies of Bystander Effects

Inom strålbehandling innebär den s.k. åskådareffekten ("bystander effect") ett relativt nytt tankesätt som betonar de biologiska effekterna av strålning på icke-bestrålade celler i närheten av bestrålade celler. Denna effekt har visat sig påverka inte bara de celler som angränsar till det bestrålade området utan även celler på större avstånd. I Lund pågår just nu ett projekt där man villPurpose Intensity modulation of radiation is one of several important conditions to evaluate for full understanding of how cells involved in the bystander effect influence each other when cells are exposed to radiation at low and high dose rates. The aim of this study was to develop and apply a useful and practical dosimetric method for measurement of the absorbed dose to cell cultures exposed to

Developement of a portable β-­‐ spectrometer for in situ measurements of Sr-­‐90 and Y-­‐90 using a plastic scintillator and a silicon photomultipler (SiPM).

Om ett kärnvapen detoneras i atmosfären eller en allvarlig kärnkräftsolycka, likt Tjernobyl, inträffar kommer radioaktivt nedfall att ske. Nedfallet innehåller radioaktiva ämnen som kommer att spridas ut över ett stort område med vind eller nederbörd. Vid denna situation är det viktigt att kunna identifiera vilka radioaktiva ämnen som finns på marken samt vilken radioaktivitet dessa har för att kuIn the event of a nuclear weapon detonation or a power plant accident radionuclides will deposit on the ground. It is then important to identify and quantify the radionuclides to obtain information necessary for radiation protection efforts like relocation and decontamination. Radiation protection instruments with beta probes can be used as search instruments but the small surface of the probe an

Mellan disciplin och dagdröm - En fältstudie av skola på ungdomshem utifrån Michel Foucault och Erving Goffman

Mina tidigare erfarenheter av att arbeta som lärare på ett statligt ungdomshem gav upphov till ett intresse att sociologiskt studera skolverksamhet i ungdomsvård. Syftet med denna uppsats är att undersöka de sociala villkor för intagna ungdomar som organiseringen av undervisningen på ungdomshem innebär, samt att undersöka hur ungdomar förhåller sig till dessa villkor genom sitt agerande. Jag utgår

Klimatanpassning i en historisk kontext- En studie om den västsvenska landsbygdens klimatanpassning och utveckling under 1800-talet.

In Sweden there are many people who take the food on our tables for granted, there is rarely anyone who reflects on the fact that it was hard work behind. The situation has not always been like that. During the late 1800s there were still many people living in rural areas and their livelihood was farming. Their jobs and mundane chore was to produce, if not the whole, but parts of the food that wou
