Does ionizing radiation affect bone marrow?
Exposure to high doses of ionizing radiation will lead to bone marrow failure and eventually death. Sub-lethal doses of irradiation will cause bone marrow suppression, which is a less severe case of bone marrow failure, and will leave a patient immunosuppressed due to an abnormal number of functional blood cells.
How does ionizing radiation affect the body?
When ionizing radiation interacts with cells, it can cause damage to the cells and genetic material (i.e., deoxyribonucleic acid, or DNA). If not properly repaired, this damage can result in the death of the cell or potentially harmful changes in the DNA (i.e., mutations).
What is the risk from exposure to ionizing and non-ionizing radiation?
We are exposed to low levels of non-ionizing radiation every day. Exposure to intense, direct amounts of non-ionizing radiation may result in damage to tissue due to heat. This is not common and mainly of concern in the workplace for those who work on large sources of non-ionizing radiation devices and instruments.
Does radiation cause bone loss?
Exposure to chemotherapy and radiation leads to bone loss and increases the risk of osteoporosis and fractures.
How does radiation help bone pain?
Radiation works by killing cancer cells, which makes tumors smaller. That can ease painful pressure on body parts in the area. Once radiation shrinks tumors enough, it can make other treatments, like surgery, more successful. If you have pain in your bones, radiation can help you move around easier.
How does radiation cause osteoporosis?
Studies in the last few years show that irradiation results in increased osteoclast number and activity as an early response, which likely contributes to radiation-induced osteoporosis [2].
Which body cells are most sensitive to ionizing radiation?
Lymphocytes (white blood cells) and cells which produce blood are constantly regenerating, and are, therefore, the most sensitive.
How does ionizing radiation damage cells?
Ionizing radiation directly affects DNA structure by inducing DNA breaks, particularly, DSBs. Secondary effects are the generation of reactive oxygen species (ROS) that oxidize proteins and lipids, and also induce several damages to DNA, like generation of abasic sites and single strand breaks (SSB).
How can non-ionizing radiation cause harm in the body?
RF energy is a type of non-ionizing radiation. Non-ionizing radiation is not strong enough to directly affect the structure of atoms or damage DNA; however, it does cause atoms to vibrate, which can cause them to heat up. When RF energy is very strong, such as from radar transmitters, it can be dangerous.
Can radiation affect bone density?
What helps bone on bone pain?
You may get temporary relief from bone pain by using over-the-counter pain relievers such as acetaminophen, aspirin, or ibuprofen. Osteomyelitis typically requires treatment with either oral or intravenous antibiotics.
Can radiation fracture a bone?
Abstract. High-dose radiation is injurious to bone and is a known risk factor for the development of late fracture. Management of radiation-induced fractures is generally thought to be difficult, with prolonged healing times and a high nonunion rate.
What differentiates between ionizing and non-ionizing radiation?
Radiation is classified as being either non-ionizing or ionizing. Non-ionizing radiation is longer wavelength/lower frequency lower energy. While ionizing radiation is short wavelength/high frequency higher energy. Ionizing Radiation has sufficient energy to produce ions in matter at the molecular level.
What is the difference between ionizing and nonionizing?
What are the biologic effects of radiation on bone?
Effects of radiation on bone Ionizing radiation produces its deleterious biologic effects by both direct (DNA strand breaks) and indirect processes (formation of free oxygen radicals). Mitotically active cells are more susceptible to the detrimental effects of ionizing radiation.

What are the possible complications of radiation therapy for osteoporosis?
Some of these complications, such as osteopenia, are reversible and severity is dose dependent. Insufficiency fractures are a common complication after radiation therapy and generally affect those bones under most physiologic stress and with the highest ratio of trabecular to cortical bone.
Can non-ionizing radiation cause damage to the body?
Exposure to intense, direct amounts of non-ionizing radiation may result in damage to tissue due to heat. This is not common and mainly of concern in the workplace for those who work on large sources of non-ionizing radiation devices and instruments.
