2002:18 A Review of Models for Dose Assessment Employed by SKB in the Renewed Safety Assessment for SFR 1
This document provides a critical review, on behalf of SSI, of the models employed by the Swedish Nuclear Fuel and Waste Management Co (SKB) for dose assessment in the renewed safety assessment for the final repository for radioactive operational waste (SFR 1) in Forsmark, Sweden. The main objective of the review is to examine the models used by SKB for radiological dose assessment in a series...

2002:17 Review of Project SAFE: Comments on biosphere conceptual model description and risk assessment methodology
The Swedish Nuclear Fuel and Waste Management Company’s (SKB’s) most recent assessment of the safety of the Forsmark repository for low-level and intermediatelevel waste (Project SAFE) is currently undergoing review by the Swedish regulators. As part of its review, the Swedish Radiation Protection Institute (SSI) identified that two components of SAFE require more detailed review: (i) the...

2002:16s Epidemiologiska studier över mobiltelefoner och risken för cancer – en översikt
Mobiltelefoner sänder och tar emot radiofrekventa signaler i frekvensområdet 450 - 2200 MHz. Elektromagnetiska vågor vid dessa frekvenser brukar kallas mikrovågor. Energiinnehållet i en elektromagnetisk våg från en mobiltelefon är några miljarder gånger lägre än i t.ex. röntgenstrålning. Den kan inte skada DNA, vilket röntgenstrålningen...

2001:11 Ethical Problems in Radiation Protection
In this report the authors survey existing international radiation-protection recommendations and standards of the ICRP, the IAEA, and the ILO. After outlining previous work on the ethics of radiation protection, professional ethics, and the ethics of human radiation experiments, the authors review ethical thinking on seven key issues related to radiation protection and ethics. They formulate...

1997:04 Magnetfält i elektriska lok
Svenska järnvägar drivs med 15 kV 16 2/3 Hz enfas växelström. l denna rapport redovisas mätningar av magnetfält vid förarplatsen i elektriska lok. Undersökningen gjordes dels i ett äldre elektromekaniskt lok, dels i olika nyare tyristorstyrda lok. Det visade sig att magnetfälten var starkare i äldre lok än i modernare loktyper. Gert Anger,...

1995:15 Determination of the Neutron and Photon Dose Equivalent at Work Places in Nuclear Facilities of Sweden
The radiation fields in nuclear power plants consist of a mixture of photons and neutrons of various energies. A detector is usually constructed to respond to one type of radiation only and is usually useful in a limited energy range . .This is especially so for neutrons. Accurate descriptions of the radiation envirorunent are therefore very complicated to obtain. During the last decade great...

1994:08 The content and environmentalimpact from the waste depositoryin Sillamae
The studies of the waste depository in Sillamae, Estonia, shows that the content as well as the wall material is typical tailings from chemical enrichment of uranium ore. The environmental impact from radioactive substances as well as heavy metals has been estimated. Results show the major radiological impact to the population in the Sillamae town is the exposure to radon and its daughter...

2020:02 Models for axial gas flow and mixing in LWR fuel rods
SSM perspective Background Fission gases inside a fuel rod plays an important role in the behaviour of the fuel, both during normal operation and during events and accidents. Fission gases are released from inside the fuel pellets to the gap between the pellet and the cladding tube and then flow to the plenum volume at the top of the fuel rod. In high burnup fuel, this axial flow to the...

2021:08 Recent Research on EMF and Health Risk, ifteenth report from SSM’s Scientific Council on Electromagnetic Fields, 2020
SSM perspective Background The Swedish Radiation Safety Authority’s (SSM) Scientifc Council on Electromagnetic Fields monitors current research on potential health risks in relation to exposure to electromagnetic fields and provides the authority with advice on assessing possible health risks. The Council gives guidance when the authority must give an opinion on policy matters when scientific...
