By coal mining and exploatation, radioactive radon gas, which is captured in natural geological structures, is reallocated from the deep coal layers. Hence it is concentrated in the depots and coal seams of the mines or being transported to the surface of the earth where it can significantly change the levels of radioactivity in the working premises and residences. This paper presents the results of a three-year research of radon activity concentration in the air in hole and surface coal mines of Bosnia and Herzegovina. Detected concentrations of radon in the coal gaseous structure, atmosphere and other ambient media are in correlation with the properties of geological structures, technology for obtaining coal and meteo-climatic changes. They were measured with Alpha GUARD PQ 2000 radon portable measuring system (instruments Genitron-Frankfurt) and RadoMeter 2000 (Radosys LTD. Budapest), using the SS-NTD method.

Radon is a unique natural element because it is an inert gas and at the same time radioactive in all of its isotopes. It is known fact that exposure of the population to high concentrations of radon gas, leads to irradiation of primarily respiratory organs, which can cause lung cancer. For reliable prospecting of radon activity concentration in the living environment, the first input parameter is the concentration of outdoor radon in the air. This paper presents the results of a three-year research of radon activity concentration in the air of Bosnia and Herzegovina. At the measurement locations were registered daily and seasonal variations of the outdoor radon concentrations, whose average values were in the range of 15-38 Bq/m3. They were measured with Alpha GUARD PQ 2000 radon portable measuring system (Genitron Instruments - Frankfurt).

Radon is a natural radioactive gas which is colorless, tasteless and odorless. Using the water which contains bigger quantities of radioactive radon might cause cancer or other health problems. This paper presents the results of radon activity concentration in spas in area of Bosnia and Herzegovina. The obtained results of radon activity concentration in thermal test samples range within the interval of (254-4,715) mBq/L, which does not exceed recommended Enviromental Protection Agency (EPA) value of 11.1 Bq/L in drinking water. The measurements of radon activity concentration are done with AlphaGUARD and AquaKIT equipment (Genitron Instruments-Frankfurt).

ITS(Internal Transcription Spacer of nuclear ribosomal DNA)regions method was applied to identify and study the phylogenetic relationships existing between 41 individuals of Crocus,including 8 species collected in Iran(4 crop and 8 wild individuals)and 16 species(2 crop and 27 wild individuals)already registered in GenBank(NCBI).PCR amplifications were performed using the primer designed on the nucleotide sequence of nuclear region(ITS).A total of 12 sequences were obtained and registered in NCBI *** particular,4 of these sequences were not already present in the scientific *** polymorphic sites were counted for ITS(N=97).The results showed that,the Cytosine base is the most abundant *** high conservation was observed in the ITS regions of the populations(0.761).Each sample could be distinguished from the others in the phylogenic trees developed based on the data obtained by ITS barcode *** general,ITS sequence indicating high resolution at the species level is very suitable for phylogenetic studies in the Crocus *** analysis demonstrated the genetic relationship between crop saffron and wild Crocus *** to the results of this study,the wild species of *** and *** were considered as the closest relatives of the *** results of the study also indicated that,the different ecotypes of *** may have evolved through independent events probably due to the geographic and environmental pressures.
