Description
All passive/open detectors, also called Unfiltered alpha Track Detectors (UTDs), are built around KODAK LR115 film, only material sensitive to all ambient alpha particles and capable to work in open mode. The principle of open detectors is not new. They are largely used worldwide, often by scientists (in France, Italy, Japan, Norway, Sweden etc.). However, their particular functioning needs some explanation and some reminders. This paper is more aimed to discuss generalities than details of calculation. The estimation of the Potential Alpha Energy (PAE) concentration is about 4 times better than that from other passive detectors and it includes thoron progeny. The film is more sensitive to ambient decay products than it is to Radon as track count is higher for alpha's of greater initial energy
