Mutations

Mutations

Mutations are changes in the sequence of DNA. These changes can occur spontaneously or they can be induced by exposure to environmental factors. Mutations can be characterized in a number of different ways: whether and how they alter the amino acid sequence of the protein, whether they occur over a small or large area of DNA, and whether they occur in somatic cells or germline cells.
Chromosomal Alterations Are Large-Scale Mutations
While point mutations are changes in a single nucleotide in...

UV–Vis Spectrometers

UV–Vis Spectrometers

The absorbance of UV and visible (UV–visible) radiations is measured using a UV–visible spectrophotometer. Deuterium lamps, which emit UV radiation, and tungsten lamps, which produce radiation in the visible region, are used as light sources in UV–visible spectrophotometers. A monochromator or prism is used for diffraction grating, i.e., to split the incoming radiation into different wavelengths. A system of slits is used to focus the desired wavelength on the sample cell. Samples for...

Ultraviolet and Visible (UV–Vis) Spectroscopy: Overview

Ultraviolet and Visible (UV–Vis) Spectroscopy: Overview

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 electronic transitions. As a result...

Biological Effects of Radiation

Biological Effects of Radiation

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 produce ions...

Absorption of Radiation

Absorption of Radiation

The rate of heat transfer by emitted radiation is described by the Stefan-Boltzmann law of radiation:

Area of Science:

Environmental Science
Public Health
Atmospheric Science

Background:

Ultraviolet (UV) radiation exposure is a significant health concern, particularly for children in outdoor school environments.
Accurate assessment of UV exposure in complex environments like schoolyards is crucial for developing effective sun protection strategies.

Purpose of the Study:

To develop and present a novel technique for modeling erythemally effective UV radiation exposure within a school environment.
To assess the influence of environmental factors on UV exposure during school meal breaks.

Main Methods:

A technique was developed to model erythemally effective UV exposure onto a horizontal plane representation of a school environment.
Input parameters included measured sky view, ground albedo, and standing surface albedo.
UV exposures were modeled for a school in Hervey Bay, Australia, during winter and summer school days.

Main Results:

The influence of tree shade and building structures varied significantly with solar zenith angle.
Horizontal plane UV exposures ranged from 0 to 7 SED (Standard Erythema Dose) at different playground locations.
The study quantified UV exposure variations based on environmental modifications.

Conclusions:

The developed technique provides a practical method for assessing UV exposure in real-world school environments.
Understanding the impact of surrounding structures on UV exposure is vital for targeted sun safety interventions.
This approach can inform school policies and infrastructure design to minimize UV risks for students.
