Summary
Climate change impacts ultraviolet (UV) radiation. This study found UV radiation in Mashhad was below global standards, with altitude and weather significantly affecting levels, not latitude or longitude.
Area of Science:
- Environmental Science
- Atmospheric Science
- Public Health
Background:
- Climate change is altering ultraviolet (UV) radiation intensity, posing risks to human health.
- Understanding regional UV radiation variations is crucial for public health and environmental monitoring.
Purpose of the Study:
- To assess UV radiation levels in Mashhad, Iran, during summer.
- To investigate the influence of geographical factors (latitude, longitude, altitude) and environmental conditions on UV radiation intensity.
Main Methods:
- A cross-sectional study was conducted in Mashhad, measuring UV-A radiation using a Hagner radiometer across 2000 stations.
- Data analysis involved SPSS software, T-tests, and ANOVA to determine the significance of various factors.
Main Results:
- The average annual UV radiation rate in Mashhad was 0.49±0.143 µSv/year, below the global standard of 10 W/m².
- Altitude and weather conditions (cloudy, semi-cloudy, sunny) significantly impacted UV radiation levels (P < 0.001).
- Latitude, longitude, and human-made artifacts showed significant influence on UV radiation intensity (P < 0.001).
Conclusions:
- UV radiation levels in Mashhad are within safe limits, suggesting open-air activities like traffic are not a significant risk.
- Altitude and meteorological conditions are key determinants of UV radiation intensity in the region.
- Further research into climate change effects on UV radiation is warranted.

02:59Biological Effects of Radiation
18.0K
All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they...

1.8K
The average temperature of Earth is the subject of much current discussion. Earth is in radiative contact with both the Sun and dark space; it receives almost all its energy from the radiation of the Sun and reflects some of it into outer space. Dark space is very cold, about 3 K, so Earth radiates energy into it. For instance, heat transfer occurs from soil and grasses, the rate of which can be so rapid that frost can occur on clear summer evenings, even in warm latitudes.

5.5K
Ultraviolet–visible (UV–visible or UV–Vis) spectroscopy is an analytical technique that investigates the interaction between matter and UV–Vis light within the electromagnetic spectrum. This method is widely used for its versatility, simplicity, and relatively quick data acquisition, making it valuable for both qualitative and quantitative analysis. When UV–Vis radiation passes through a material, molecules absorb light depending on the energy required for...

64.0K
The rate of reaction is the change in the amount of a reactant or product per unit time. Reaction rates are therefore determined by measuring the time dependence of some property that can be related to reactant or product amounts. Rates of reactions that consume or produce gaseous substances, for example, are conveniently determined by measuring changes in volume or pressure.
The mathematical representation of the change in the concentration of reactants and products, over time, is the rate...

01:09Radiation Pressure: Problem Solving
848
The radiation pressure applied by an electromagnetic wave on a perfectly absorbing surface equals the energy density of the wave. The wave's momentum also gets transferred to the surface when an electromagnetic wave is entirely absorbed by it. The rate at which momentum is transmitted to an absorbing surface perpendicular to the propagation direction equals the force on the surface.
The average value of the rate of momentum transfer divided by the absorbing area represents the average force...
