This paper describes how Radiation affects the body, the somatic and genetic effect that can occure in exposure of ionizing Radiation and how to protect yourself against it. How Radiation affects the cells and why you can get cancer if you get exposed of a large amount of Radiation is mentioned. Research after a threshold is mentioned and what Sweden does today to improve the Radiation protection by laws and regulations. Explaining the atom, what Radiation is and how the ionizing radation interacts with the atom. How backscatter affect the picture and the workers and how to protect yourself from backscatter is mentioned. Radiation doses, dosimetry and rules for those who practise Radiation is shortly described..

The objective of this thesis is to make a training material for KSU, which shows how Radiation affects the different electronic components in a radiological environment.All electronic systems in the presence of high ionizing Radiation can experience difficulties and be destroyed.This influence may compromise the control system and thus the safety of a nuclear reactor plant.To achieve this objective requires a description of electronic components and sensors, to better understand its function.This thesis will also show the possible solutions available that the author found interesting.Organizations such as NASA, CERN and ESA have worked to develop electronic components immune to Radiation. Those organizations have also developed a test protocol that guarantees to a certain extent the security of electronic components in a radiological environment.Since we know how the material reacts with the Radiation, it could develop a material that can be resistant to Radiation or like CMOS technology has proposed, to reduce the component to avoid the storage of charge in the oxide.Another solution can be the GRAPHENE. Its features will revolutionize the electronics and provide answer to the Radiation problems, Graphene will replace Silicium and the electronic components will only have a few nanometers dimensions so the oxide area also reduces, and in this way avoid the known problem of storage of charge..

The purpose with this examination is to build a measureequipment to AerotechTelub AB (AT), who will registrate fault in SRAM-memory in contact with cosmic Radiation. The equipment will be created around developcard from Memec Design with FPGA from Xilinx. The logic in the FPGA will be implemented with the hardwaredescribed language VHDL. The SRAM-memory that will be tested is build in CMOS-teknologi. The memorycells will be loaded with a predecided bitpattern.

Cancer is one of the most feared diseases in veterinary medicine today, and the incidence is higher than ever due to the fact that our companion animals live longer then they did ten to twenty years ago. Cancer is also one of the most common causes of mortality in older companion animals. This literature review will be about two of the currently most common form of cancer treatment of companion animals in Swedish animal hospitals, chemotherapy and Radiation therapy. There will also be a section of general nursing care for cancer patients. The section of chemotherapy will describe the indications for choosing chemotherapy, the way to administrate chemotherapeutic drugs, describe specific chemotherapeutic drugs, potential side effects of chemotherapy, and how to handle and store chemotherapeutic drugs safely. The section of Radiation therapy will describe the current devices for delivering Radiation therapy, describe the indications for choosing Radiation therapy and describe potential side effects that Radiation therapy may cause.

In this report an MCNP (Monte Carlo N-Particle) model is described for the reactor vessel at Ringhals 2. The model is validated against the specific activity in neutron dosimeters, extracted in 1977, 1984 and 1994. The validation showed that the calculations of the model are within the requirements of a maximum of 20 percent uncertainty for every neutron dosimeter except one, extracted after the first cycle. The uncertainty of this cycle was mostly due to the operation data rather than to the MCNP model.The model has been used to investigate various questions concerning Radiation damage. The reliability of the traditional measure of Radiation damage, fast neutron flux (En > 1MeV) has been evaluated.  This has been done by taking the ratio for this and another measure of Radiation damage, DPA (Displacement Per Atom), for various positions and layers.

X-rays are a potential risk for animal health care personnel. The present study will examine the risks for scattered Radiation to the personnel, if no lead gloves are used when holding an animal during the x-ray examination. Furthermore, how the impact of the exposure values and body parts examined, affect the scattered dose to the hands of the holder. Also, the distance between the animal and the hand that holds it was evaluated to see the impact on scattered Radiation exposure. Tested by a survey, to animal health care students, the frequency of the usage of lead gloves in Swedish animal hospitals was studied. According to the results from the analysis, animal health care personnel don't need to use lead gloves every time they hold an animal or a cassette during x-ray examinations.

The aim of this thesis is to investigate the electric solar potential on the Swedish island Gotland. The Gotlandic habitations have been divided into four house categories. For each category energy demand, roof area, geographic orientation androof tilt have been decided. Solar Radiation data have been collected from the Swedish solar Radiation model STRÅNG (STRÅNG, 2012).The buildings characteristics and the solar Radiation have been used as input values in common solar formulas, the solar potential for each building category have been summed up to a total electric solar potential for the region.The electric solar potential on Gotland was calculated to 242 GWh/year with solar data from 2010. Gotlands largest city, Visby, is marked as cultural heritage by UNESCO (UNESCO, 2012).

Jönköping Small Animal Hospital is today the only clinic in Sweden to offer Radiation therapy as a treatment of tumours. The body contains of billions of cells that all have to obey the regulations that are established. If a cell is exposed to a harmful substance, for example a chemical, it can be transformed into a tumourcell. Normally the body has a good defence but the tumourcell can survive and start to divide unrestrained. A tumour is starting to develop.

AbstractClimate and environmental issues are of paramount importance. Researchers agreethat we must all contribute to a reduction of gases that contribute to climatechange. Energy consumption must decrease within all sectors and the promotionof renewable sources of energy must be introduced.Each sector should aspire to decrease its energy consumption. Energyconsumption is strongly linked to waste gases that contribute to climate change.Passive houses are a part of the construction industry's methods to attain energyconservation.Passive houses are derived from low energy houses and super insulated houses. Apassive house is intended to obtain heat from the inhabitants and through theiractivities.

One part of preventive conservation is controlling the lighting in the exhibitions. As a first step we have to accept the fact that the very act of displaying objects is causing them damage, and because the trend is for everything to be open to the public view all the time, the aim is to minimize light exposure of exhibits.This essay will present lighting options and relate them to the current recommendations. I have put the emphasis upon describing which methods one can use to minimize the degradation of exhibits on display by eliminating UV- and IR-Radiation and reducing the visible light. The intention with this essay is to investigate the current lighting options and compare these to the recommendations on lighting exhibitions.The selections of different lighting options such as LED-, halogen- and energysaving lamps were made based on avaibility. Thereafter I did two types of investigations.

Introduction: Each year 1200-1300 patients are diagnosed with head neck cancer. Treatment that involves radiotherapy can cause severe side effects for example trismus that affects quality of life.Purpose: To study health-related quality of life in patients who have undergone Radiation treatment for head and neck cancer and participated in a intervention group who received training intended to prevent trismus or in a control group who received standard treatment.Method: This is a prospective study in which data is collected from 66 patients participating in a randomized study aiming to evaluate a training program to prevent trismus. Thirty three participated in the intervention group and thirty three in the control group. Both patient groups assessed health related quality of life (HRQOL) with EORTC QLQ C30 and QLQ-H&N35, at start and end of the Radiation treatment, and at 3 and 6-months after completing Radiation treatment.Results: There is no difference between the intervention and control groups regarding symptoms, functional status and global health, except for intake of nutritional supplements.  For both groups almost all scales measuring HRQOL deteriorated under the Radiation treatment. However, 3 and 6 months after end of radiotherapy HRQOL had improved and had returned to the baseline values.

Background: Chemotherapy and Radiation resistance are major causes of failure in cancer treatment. The response to treatment in cancer cells depends on several mechanisms and pathways such as Janus kinases-signal transducers and activators of transcription JAK/STAT pathway. STAT1 was the first described transcription factor in the STAT family. STAT1 is activated by stimulation of signaling proteins such as type II interferon (IFN- ?) and the activated STAT1 translocates from cytoplasm to nucleus.

The control of indoor temperature must be able to handle large time constants and both measureable disturbances like outdoor temperature, and non-measurable disturbances, like waste heat from appliances. Due to cheaper microcontrollers (small computers with designated tasks) with better performance, more advanced and computation-demanding methods for control can be used.In this thesis, Generalized Predictive Control (GPC) has been implemented and tested on a theoretically derived model of a house. GPC states that a model of the system is estimated in every sample, and the control is carried out simultaneously, based on predictions of the model. Disturbances like solar Radiation can be estimated and used in the control as well. The control signals are determined by quadratic programming, which makes it possible to consider conditions, for example limitations on the control signals.GPC requires a number of parameters to be defined, like model order and control signal penalty, but is relatively robust for variations in them.

This thesis work was made to optimize the writing of the construction specificationsat FKA. These construction specifications are created before each plant modificationsthat is started because requirements from the Swedish Radiation safety authority(SSM) and internally on Forsmarks nuclear group as constructions / implementationdocumentationThe study was done through seven interviews of two people at three different groupsinvolved in the construction specification and an interview from the group accreditedverification. The four selected groups were selected through an extensive analyticalwork resulted in an elimination matrix where these four groups was considered to bemost involved with the construction specification.The questions asked to these individuals were based on the instructions and sampletext that are described in the construction specification. To ensure the quality of thethesis were to limit itself to the chapters that were considered most relevant toimprove. The analysis revealed a number of points that should be improved, partlyinto the routines when writing the construction specification and when ether sampletext or suggestions should be changed and complemented.
