Published on: July 3, 2015
Summary
Fall-out radioactivity, including strontium-90 and caesium-137, was measured in Greenland in 1976. These levels were assessed in various environmental samples and the human diet.
Area of Science:
- Environmental Science
- Radiochemistry
- Public Health
Background:
- Radioactive fall-out monitoring is crucial for assessing environmental contamination.
- Understanding radionuclide levels in Greenland provides insights into global fall-out patterns.
Purpose of the Study:
- To report measurements of fall-out radioactivity in Greenland for the year 1976.
- To quantify strontium-90 and caesium-137 in environmental and dietary samples.
Main Methods:
- Analysis of samples including precipitation, seawater, vegetation, animals, and drinking water.
- Determination of strontium-90 and caesium-137 concentrations.
Main Results:
- Strontium-90 and caesium-137 levels were quantified in various environmental matrices.
- Estimates of mean dietary intake of these radionuclides for the Greenland population in 1976 were calculated.
Conclusions:
- The study provides essential data on the 1976 fall-out radioactivity levels in Greenland.
- Findings contribute to the ongoing assessment of radionuclide exposure in Arctic regions.

03:23Types of Radioactivity
The most common types of radioactivity are α decay, β decay, γ decay, neutron emission, and electron capture.
Alpha (α) decay is the emission of an α particle from the nucleus. For example, polonium-210 undergoes α decay:

02:48Radioactive Decay and Radiometric Dating
Radioactivity is a spontaneous disintegration of an unstable nuclide and is a random process, as all the nuclei in the sample do not decay simultaneously. The number of disintegrations per unit time is called the activity (A), which is directly proportional to the number of nuclei in the sample. The decay constant (λ) is an average probability of decay per nucleus in unit time.
02:59Biological 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...
01:17Radiation: Applications
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.

01:18Other Unique Bacteria
Magnetic bacteria exhibit a directed movement called magnetotaxis, driven by structures called magnetosomes. These magnetosomes consist of chains of magnetic particles made of either magnetite (Fe₃O₄) or greigite (Fe₃S₄) and are organized in a linear conformation by a protein scaffold within invaginations of the cell membrane. The bacteria align along the north–south magnetic field lines, much like a compass needle. They are typically microaerophilic or anaerobic and are commonly found near the...
01:21Green Algae
Green algae, also referred to as chlorophytes, are different from red algae in having the chloroplasts containing chlorophylls a and b, which give them their distinct green hue. However, they lack phycobiliproteins, preventing them from developing the red or blue-green pigmentation seen in red algae. In terms of photosynthetic pigment composition, green algae closely resemble plants and share a close evolutionary relationship with them. Taxonomically Green algae belong to Phylum Chlorophyta in...
