“…• Environmental Analysis ENGs have been used in non-destructive measurements with neutron inelastic scattering activation analysis and PGNAA to detect and quantify hazardous elements in the soil at contaminated locations. [345][346][347] In the United States an important list of hazardous elements is defined by the resource conservation and recovery act (RCRA) guidelines for dealing with hazardous waste, included in this list are the heavy metal elements including As, Ba, Cd, Cr, Pb, Hg, Se, and Ag. Neutron-based techniques have also been developed to assay RCRA elements in waste barrels using PGNAA methods.…”

Advances in neutron science have gone hand in hand with the development and of particle accelerators from the beginning of both fields of study. Early accelerator systems were developed simply to produce neutrons, allowing scientists to study their properties and how neutrons interact in matter, but people quickly realized that more tangible uses existed too. Today the diversity of applications for industrial accelerator-based neutron sources is high and so to is the actual number of instruments in daily use is high, and they serve important roles in the fields where they're used. This chapter presents a technical introduction to the different ways particle accelerators are used to produce neutrons, an historical overview of the early development of neutron-producing particle accelerators, a description of some current industrial accelerator systems, narratives of the fields where neutron-producing particle accelerators are used today, and comments on future trends in the industrial uses of neutron producing particle accelerators.

“…Uranium as a heavy metal is a natural constituent of the earth's crust and the presences of it in soil are natural and anthropogenic when the main sources of anthropogenic exist in various industrial sources and agricultural activities such using fertilizer while the result of these activities are causing to soil pollution by these types of heavy metals. The maximum permissible levels of metal concentrations in soil were complying with the idea of preventing toxic exposure of plants, animals and humans [4]. Generally, the distribution of such heavy metals is influenced by kind of main source, climate and relative mobility depending on soil parameters such as mineralogy, texture and category of soil and PH [5].…”

The profile of radon (222-Rn) and uranium (238-U) concentrations in15 surface soil samples collected from the three agricultural areas of town Qadafery, Kalar and Zarayan which are located at the east of Sulaimani governorate in Kurdistan Region-Iraq has been determined using solid-state nuclear track detector (CR-39), where Qadafery located in the margin of Suren Mountain, also located in the north of the famous plain of the Middle East region called Sharazoor plain and Zarayan located in the west north of the Sharazoor plain, also its surrounds in another direction by Qaradagh and Barznja mountains. They (Qadafery, Kalar and Zarayan) have been shown that the maximum and minimum values of radon concentration of the air inside the tube were 2242.263±143.152 Bq/m^3 and 154.099±2.579 Bq/m^3, respectively, with average value 741.709±27.234 Bq/m^3 while the maximum and minimum values of uranium concentration are 18.225±12.905 ppm and 1.253±0.233 pmm, respectively, with average value 6.029±2.455 pmm. It appears that higher concentrations of radon and uranium was in soil sample Qadafery_5 and the minimum value was in soil sample Kalar_4 and by comparison with the world values there are some positions in Qadafery and Zarayan with higher level concentrations that is due to the geology information of these regions.

In this study, the CR-39 detector technique was used, to estimate the uranium concentration from the soil in midland refineries Company (Doura refine (, Baghdad, Iraq. Uranium concentrations in soil samples have been measured using solid state nuclear track detector type CR-39. Nine soil samples were collected from different areas within the Doura refinery and other soil samples were collected form Abu Tayara Street and ALshortaa District outside the refinery for comparison. The results showed variable values for uranium concentrations. The average value of uranium concentration was found to be 0.37 ppm in doura refinery. For areas outside the refinery, the concentration of uranium was 0.008 ppm. These results were less than the global limit.
