The primary goal of this PhD research was to obtain critical information needed to further calibrate the novel glass-based retrospective radon detectors (RRDs) by characterizing the quantitative relationship between radon gas concentrations, the surface-deposited activities of various radon progeny, the airborne dose rate, and various residential environmental factors through both actual field ...

Legacy landmines in post-conflict areas are a non-discriminatory lethal hazard and can still be triggered decades after the conflict has ended. Efforts to detect these explosive devices expensive, time-consuming, dangerous humans animals involved. While methods such as metal detectors sniffer dogs have successfully been used humanitarian demining, more tools required for both site surveying acc...

Within the framework of the grant of the Polish Ministry of Science and Higher Education entitled Seasonal changes of indoor radon (222Rn) concentrations of Poland (N506 1127 33) radon laboratories united in the Radon Center – the Non-governmental International Scientific Network – perform measurements of radon concentration in houses located in various areas of Poland. These laboratories belon...

Single plane illumination microscopy based fluorescence correlation spectroscopy (SPIM-FCS) is a new method for imaging FCS in 3D samples, providing diffusion coefficients, transport, flow velocities and concentrations in an imaging mode. SPIM-FCS records correlation functions over a whole plane in a sample, which requires array detectors for recording the fluorescence signal. Several types of ...

The study investigates the development of sensors, in particular the use of thermo-fluidic sensors and occupancy detectors, to achieve smart operation of air conditioning systems. Smart operation refers to the operation of air conditioners by the reinforcement of interaction to achieve both thermal comfort and energy efficiency. Sensors related to thermal comfort include those of temperature, h...

In this paper, we propose and study a method using bare LR 115 SSNTDs for passive monitoring of the equilibrium factor F inside a radon exposure chamber. The method is based on the proxy equilibrium factor Fp which is defined as Fp 1⁄4 r=ðriC0tÞ 1, where ri is the partial sensitivity (i.e., the number of tracks per unit area per unit exposure), C0 is the radon gas concentration and t is the exp...

Fission track dating has greatly expanded its usefulness to geology over the last 40 years. It is central to thermochronology—the use of shortened fission tracks to decipher the thermal history, movement, and provenance of rocks. When combined with other indicators, such as zircon color and (U–Th)/He, a range of temperatures from 40 ◦C to 400 ◦C can be studied. Combining fission track analysis ...
