Komunikacja ze społeczeństwem w obszarze bezpieczeństwa publicznego
Organizacje, w których działalność wpisane jest zapewnienie bezpieczeństwa publicznego,
powinny w swojej strategii dbać o otoczenie i komunikację z nim, ponieważ
w tym obszarze odbywa się nie tylko budowanie wizerunku organizacji i jej
reputacji, ale także relacje z społeczeństwem wpływające na ostateczny kształt
tych organizacji w obszarze bezpieczeństwa publicznego. Badając ten obszar, należy
zwrócić uwagę na kwestie związane z PR, z marketingiem i na analizę informacji
z mediów, które mają wpływ na kształtowanie wizerunku organizacji zajmujących
się bezpieczeństwem publicznym oraz na postawy społeczne.Organizations whose main activity is public safety should in their strategy care
about their surroundings, relations with surroundings, because in this field building
the image of the organization and its reputation as well as relations with the society
influence the ultimate shape of these organizations in the public safety field. Studying
this field we should pay attention to issues associated with PR, marketing and
the analysis of the information from the media, which have impact on shaping the
image of organizations dealing with the public safety and social attitudes.Организации, которые занимаются обеспечением общественной безопасности,
должны в своей стратегии учитывать необходимость заботы о окружении
и установлении с ним соответствующих связей. Создание хорошего облика организации, её репутации и установление связей с общественностью имеет
большое влияние на комплексное восприятие этих организаций в пространстве
общественной безопасности. Исследуя эту проблему, необходимо обратить
внимание на вопросы связанные с РЯ-деятельностью, маркетингом и анализом
данных поступающей со средств массовой информации, которые имеют влияние
на формирование общественного мнения о организациях, занимающихся
общественной безопасностью и на отношение к ним всего общества
Test measurements of thoron concentration using two ionization chambers AlphaGUARD vs. radon monitor RAD7
The experiment aiming at testing the possibility of using AlphaGUARD monitors based on an ionization
chamber for thoron measurements is presented. A single AlphaGUARD monitor working in the flow mode was applied to measure thoron concentration in the radon-free atmosphere. The sensitivity (correction factors) of the monitor to thoron was estimated by comparison with a RAD7 portable detector (Durridge Company), based on spectrometric analysis, in the thoron, radon-free atmosphere in a calibration chamber. This depends on the applied flow rate and changes from 8% for the flow rate of 0.3 dm3/min to 36% for 1 dm3/min. It was also revealed that the sensitivity of the monitor to thoron in the diffusion mode is equal to ca. 5% and may be neglected. The method involving two Alpha-GUARD monitors working in two different modes (diffusion and flow) at the same time may be used to evaluate radon and thoron concentration in the natural environmental conditions where usually both isotopes appear together. In this method thoron concentration is estimated as the difference of results obtained from two AlphaGUARD monitors multiplied by the correction factor corresponding to the applied flow rate. The devices based on spectrometric analysis, e.g. RAD7 seem to be a better tool for thoron measurements in the environmental conditions
Investigation of the influence of chamber construction parameters on radon exhalation rate
Radon exhalation from ground is a process dependent on the emanation and migration of radon through ambient air. Most studies on radon exhalation from soil were performed regarding the influence of meteorological and soil parameters. As radon exhalation rate can be affected by the internal properties of the sample, it may also be influenced by the exhalation chamber geometry such as volume-to-area (V/S) ratio or other construction parameters. The measurements of radon exhalation from soil were made using different constructions of accumulation chamber and two types of radon monitors: RAD7 (Durridge) and AlphaGUARD PQ2000PRO (Genitron). The measurements were performed on one site in two locations and approximately at the same time. The first tests did not show the correlations of exhalation rate values and the chamber's construction parameters and their geometrical dimensions. However, when examining the results, it seems that there are still too many factors that might have affected the process of radon exhalation. The future experiments are planned to be conducted in controlled laboratory conditions
Vitamin D Status and its Relation to Exercise Performance and Iron Status in Young Ice Hockey Players
Objectives The aim was to examine the association between serum vitamin D concentration and isometric strength of various muscle groups, vertical jump performance, and repeated sprint ability in young ice hockey players. The secondary aim was to determine the association between vitamin D deficiency and indices of iron status.
Methods Fifty male ice hockey players (17.2±0.9 years) participated in this cross-sectional study. Exercise performance was evaluated using isometric strength measures of upper and lower extremities, vertical jump performance and repeated sprint ability (RSA). Blood samples were collected for the determination of serum 25-hydroxyvitamin D (25(OH)D) and multiple indicies of iron status.
Results The mean serum 25(OH)D concentration was 30.4 ng-ml-1 and ranged from 12.5 to 91.4 ng-ml-1. Eleven participants (22%) had vitamin D deficiency and 20 athletes (40%) had vitamin D insufficiency. Serum 25(OH)D concentration was not positively correlated with isometric muscle strength, vertical jump performance, or RSA after adjusting for age, training experience, fat mass, fat free mass and height. Serum 25(OH)D concentration was not associated with indices of iron status.
Conclusion Vitamin D insufficiency is highly prevalent in ice hockey players, but 25(OH)D concentration but it is not associated with exercise performance or indices of iron status

Współczesne wyzwania teorii i praktyki bezpieczeństwa
Z wprowadzenia: "Nauki o bezpieczeństwie mają niespełna sześcioletnią historię, kiedy to 8 sierpnia
2011 roku minister Nauki i Szkolnictwa Wyższego ustanowiła je swoim rozporządzeniem

National comparison of methods for determination of radon in water
The article describes three interlaboratory experiments concerning 222Rn determination in water samples.
The fi rst two experiments were carried out with the use of artifi cial radon waters prepared by the Laboratory
of Radiometric Expertise (LER), Institute of Nuclear Physics, Polish Academy of Sciences in Kraków in 2014
and 2018. The third experiment was performed using natural environment waters collected in the vicinity of the
former uranium mine in Kowary in 2016. Most of the institutions performing radon in water measurements in
Poland were gathered in the Polish Radon Centre Network, and they participated in the experiments. The goal of
these exercises was to evaluate different measurement techniques used routinely in Polish laboratories and the
laboratories’ profi ciency of radon in water measurements. In the experiment performed in 2018, the reference
values of 222Rn concentration in water were calculated based on the method developed at LER. The participants’
results appeared to be worse for low radon concentration than for high radon concentrations. The conclusions
drawn on that base indicated the weaknesses of the used methods and probably the sampling. The interlaboratory
experiments, in term, can help to improve the participants’ skills and reliability of their results
Radon intercomparison tests – Katowice, 2016
At the beginning of the year 2016, the representatives of the Polish Radon Centre decided to organize
profi ciency tests (PTs) for measurements of radon gas and radon decay products in the air, involving radon
monitors and laboratory passive techniques. The Silesian Centre for Environmental Radioactivity of the Central
Mining Institute (GIG), Katowice, became responsible for the organization of the PT exercises. The main reason
to choose that location was the radon chamber in GIG with a volume of 17 m3, the biggest one in Poland. Accordingly,
13 participants from Poland plus one participant from Germany expressed their interest. The participants
were invited to inform the organizers about what types of monitors and methods they would like to check during
the tests. On this basis, the GIG team prepared the proposal for the schedule of exercises, such as the required
level(s) of radon concentrations, the number and periods of tests, proposed potential alpha energy concentration
(PAEC) levels and also the overall period of PT. The PT activity was performed between 6th and 17th June
2016. After assessment of the results, the agreement between radon monitors and other measurement methods
was confi rmed. In the case of PAEC monitors and methods of measurements, the results of PT exercises were
consistent and confi rmed the accuracy of the calibration procedures used by the participants. The results of the
PAEC PTs will be published elsewhere; in this paper, only the results of radon intercomparison are described
