Both the description of and the operational experience with the radiation protection system at the research reactor WWR-M are presented. The list of the factors regarding the radiation hazards during the reactor routine operation is given and the main activities on the radiation safety provision are established. The statistical information for the staff exposure, the radioactive aerosol releases and the external radiation monitoring is shown. The preliminary considerations on the system upgrading for the decommissioning are presented.

Due to misconceptions surrounding radiation and nuclear energy, educating the general public about basic radiation concepts has become increasingly important. The Virtual Education and Research Laboratory (VERL) at the University of Illinois at Urbana-Champaign (UIUC) has developed a 3D, virtual, interactive game that conveys the physics of radiation and principles of radiation protection to the player. The model is a scavenger hunt style game that takes place in a virtual model of a TRIGA research reactor. Several virtual radiation sources are placed in the 3D virtual model of the TRIGA facility. Radiation drops away from the radiation source. The effect of shielding can also be incorporated in modeling the radiation transport, leading to realistic radiation fields. The user’s goal is to find and collect (virtual) objects placed in this facility while minimizing the dose received in doing so. The player is meant to learn about time, distance, and shielding — key concepts in radiation protection. The start screen displays the radiation field in the form of a colored coded floor, as well as the location of the desired objects. With the given information, the player is encouraged to plan the route to collect the items and minimize exposure. By repeatedly playing the game, the player becomes familiar with the layout of the facility, and of the location of the radiation sources. This educational game is a useful teaching tool. Those unfamiliar with radiation protection concepts are able to understand how important time, distance, and shielding are in minimizing dosage. Additionally, this game proves to be a useful engagement and outreach tool. Upon completion of the game, the user is shown the score, the dose received, as well as a list of dose received in well-known instances such as eating a banana or in getting an x-ray at the dentist’s office. The dose minimization game developed earlier for computers has now been developed for use as a game-app for cell phones. These recent developments allow for wider outreach, further increasing the use of the model as an outreach and educational tool.

The fundamental practical principles applied to any radiation protection problem are discussed. Types of radiation that may be encountered include α‎-particles, β‎-particles, γ‎-rays, neutrons, X-rays, or a combination. Each presents its own particular practical problems in terms of radiation protection, and the properties and practical principles that should be considered for each are outlined. The framework required to manage radiation protection and the practical techniques important in restricting exposure are discussed. The practical control measures of time, distance, and shielding that are invoked to restrict exposure from external radiation are considered for each type of radiation. Methods for limiting intake of radioactive material through ingestion, inhalation, and absorption to minimize internal exposure are described.

Justification, optimization, and limitation are the three underlying principles of good radiation protection. This chapter considers how these principles apply in a variety of exposure situations. Risk-based application of the principles results in control methods comprising control over areas, control over people, and control over radiation sources. These are implemented through judgements based on the use of dose limits, dose constraints, and application of the ALARA principle. Potential dose levels and possible control measures appropriate to each situation are reviewed and evaluated in risk assessments prior to work being undertaken.
