Description

Radiation Technologies in Environmental Science have demonstrated diverse developmental directions. This study focuses on and examines outcomes that have led to advanced technological solutions. The use of ionizing and non-ionizing radiation to monitor, treat, or analyze environmental components, nowaday, is extremely important. These methods are often non-invasive and highly sensitive.
Applications of Radiation Technologies in Environment Sciences are grouped into Pollution Monitoring, Waste Treatment, Soil and Groundwater Remediation and Climate Studies. In the Pollution Monitoring the Remote Sensing and Radiotracers are used to monitor air and water quality, to track pollutant pathways in air, water, and soil systems. In the Waste Treatment the Gamma Irradiation is used to Destroy pathogens and organic pollutants in wastewater and sludge, the Electron Beam Processing is effective in degrading toxic chemicals like phenols and dyes in industrial effluents. The Soil and Groundwater Remediation uses Radiolysis with the help of which the high-energy radiation breaks down hazardous organic compounds in contaminated soil and groundwater. In the Climate Studies the Radiative forcing models use data about how different gases absorb and emit radiation to predict climate change.
The benefits of using radiation technologies are underlined and those are: non-invasive and real-time data collection; high precision and sensitivity; capabilities of treating contaminants without adding chemicals. The radiation technologies come across with risks and limitations such as radiation exposure risks for workers and nearby populations, high initial infrastructure cost, regulatory and waste disposal challenges. Radiation technologies support countries in using gamma irradiation for sewage sludge disinfection and use spectral radiation data for monitoring greenhouse gases and deforestation.
Here comparative analysis are presented, the opportunities for capacity enhancement are highlighted, and the potential for future local production of such high-tech devices are discussed.
