The concept of radiation protection culture, proposed by French Society for Radiation Protection (SFRP) and then launched by International Radiation Protection Association (IRPA) is presented. The paper is focused on the role of radiation culture in preventing unjustified fear associated with the use of radiation. Principles of RP culture and optimization of radiation protection, as well as the problems how RP culture can be learned and how to engage the stakeholders are considered.

The paper presents a newly designed ionisation chambers containing boron, operated in the initial recombination regime. The chambers were either filled with BF3 or the chamber electrodes were covered with B4C. The chambers can be placed in paraffin moderators. The sensitivity of the chambers was investigated depending on gas pressure, moderator thickness and polarizing voltage. The results showed that it was possible to obtain nearly the same sensitivity of the chamber to H* (10) for photons and neutrons in restricted energy range, however further investigations are needed to make an optimum design. The examples of applications for dosimetric measurements in mixed radiation fields near medical linear accelerator and in the vicinity of high-energy proton accelerator are presented.

A ionization chamber, filled with 10BF3 and operating in a pulse mode, was investigated as a possible sensitive pocket detector for detection of neutrons at low flux densities. The chamber is 85 mm long and 19 mm in diameter. The measured sensitivity of the chamber placed near the human body (in the belt), without any additional moderator was of the order of 1 pulse/n cm-2 in the radiation field of a 252Cf source.

Recombination chambers and 2202D Studsvik-Alnor reference remmeter were used for determination of ambient dose equivalent, H*(10) and its neutron and gamma components at the door to the maze of 15 MV medical accelerator. The measurements were performed at opened and partly closed door. The results showed that the ambient dose equivalent rate was 76.2 μSv h-1 at the opened door and only 2.7 μSv h-1 at slightly opened door, 2.5 m from the entrance to the maze.
