Radiation and electrons bombarded by radiation move haphazardly inside the cell, resulting in damage to the various molecules forming the cell. Chromosomal DNA inside the cell nucleus can also be damaged.
Why does nuclear radiation sometimes damage cells?
Regardless of the form it takes, all nuclear radiation has enough energy to strip electrons off atoms and molecules that it interacts with, earning it the name ionising radiation. It is this electron-stripping (ionising) property that does the damage to our cells and tissues.
What does nuclear radiation do to living cells?
Ionizing radiation can affect the atoms in living things, so it poses a health risk by damaging tissue and DNA in genes. has sufficient energy to affect the atoms in living cells and thereby damage their genetic material (DNA). Fortunately, the cells in our bodies are extremely efficient at repairing this damage.
Does radiation destroy your cells?
Radiation can kill cells by two distinct mechanisms. The first is apoptosis, also called programmed cell death or interphase death. Cells undergoing apoptosis as an immediate consequence of radiation damage usually die in interphase within a few hours of irradiation, irrespective of and without intervening mitosis.
How does radiation affect non living things?
Long-term or high-dose exposure to radiation can harm both living and nonliving things. Radiation knocks electrons out of atoms and changes them to ions. It also breaks bonds in DNA and other compounds in living things. One source of radiation that is especially dangerous to people is radon.
How does radiation damage tissue?
The source of such radiation is usually either nuclear (e.g. radioactive material) or cosmic rays. When charged particles travel through tissue they damage tissue by stripping electrons from atoms and molecules, thus destroying their ability to function.
Why is radiation bad for the environment?
Plants and animals within the affected area take up radioactive particles, and these move through the ecosystem through bioaccumulation. Radiation pollution within waterways also accumulates within fish and other aquatic organisms, and runoff from radiation within the soil provides additional contamination.
Why is nuclear energy bad for the environment?
Nuclear energy produces radioactive waste A major environmental concern related to nuclear power is the creation of radioactive wastes such as uranium mill tailings, spent (used) reactor fuel, and other radioactive wastes. These materials can remain radioactive and dangerous to human health for thousands of years.
How does radiation affect cells and tissues?
High doses tend to kill cells, while low doses tend to damage or change them. High doses can kill so many cells that tissues and organs are damaged. This in turn may cause a rapid whole body response often called the Acute Radiation Syndrome (ARS).
Why does radiation damage tissue?
The source of such radiation is usually either nuclear (e.g. radioactive material) or cosmic rays. When charged particles travel through tissue they damage tissue by stripping electrons from atoms and molecules, thus destroying their ability to function.
