Nuclear radiation can be harmful to living things because the radiation can change a living thing's physical structure. The radiation can breakdown cell molecules, when this happens the cell cannot replicate itself. Because the cell is unable to replicate itself properly this can cause it to be more vulnerable to diseases such as cancer.

Which of the following cell types are least sensitive to ionizing radiation damage?
Red blood cells are the least sensitive to ionizing radiation damage because they lack a nucleus and are unable to repair DNA damage caused by radiation exposure. This also makes them unable to undergo cell division or replication.
How can radioactive fallout affect the human body?
The high energy particles (alpha and beta radiation) and electromagnetic waves (gamma radiation) damage large molecules in cells, which usually kills or badly damages the cells themselves. If cells die on such large scale it can lead to multiple organ failure. radiation damage to skin cells often becomes a sort of burn. In smaller doses radiation can still damage DNA, which can lead to cancer.
What types of cells are most sensitive to radiation damage?
Rapidly dividing cells, such as those in the bone marrow, gastrointestinal tract, and hair follicles, are the most sensitive to radiation damage. These cells are actively undergoing mitosis and are therefore more susceptible to the effects of radiation.
What makes tumor cells radiosensitive?
Simply: tumor cells tend to be more radiosensitive because they spend more time on average undergoing uncontrolled mitosis than normal cells. Since mitosis is the most sensitive phase of the cell cycle (phase through which the cell is most easily lethally damaged by radiation), their risk is increased. On another note, depending on which genes are causing the cell to become cancerous, certain blockers that would prevent a cell whose DNA had been damaged by radiation might not stop that cell from moving into mitosis, failing, and committing apoptosis (preprogrammed cell death).
Which of the following cell types are at least sensitive to ionizing radiation damage?
All of the following cell types can be sensitive to ionizing radiation damage: Stem cells: can be more sensitive because they are actively dividing. Rapidly dividing cells: such as those in the skin, digestive tract, and bone marrow. Cancer cells: due to their increased rate of cell division compared to normal cells.
What makes ionizing radiation the most dangerous type of radiation?
Ionizing radiation is the most dangerous type of radiation because it has enough energy to remove electrons from atoms, leading to damage in cells and DNA, which can cause serious health effects like cancer.
Why radioactivity can cure some type of cancer?
The radiation itself is not the cure. Radioactive radiation is dangerous and kills cells and potentially causes cancer. The radiation is used to kill the cells comprising the cancer (and some of the cells round the cancer). The treatment is very brutal (it makes the patient very ill for a time) but, where the cancer can not be cut out surgically the radiation beams can sometimes be used and in this case, while using them is dangerous, their use can be beneficial in the long run.
What is radiation and why is it dangerous?
Radiation is the emission of energy in the form of waves or particles. It can be dangerous because it can damage cells and DNA in the body, leading to health problems such as cancer and radiation sickness.
Which is the most penetrating and dangerous radiation?
Gamma radiation is the most penetrating and dangerous form of radiation. It can travel long distances through air and penetrate materials easily, which makes it more hazardous to human health.
Is gamma radiation the most dangerous kind of radiation?
Gamma radiation is considered among the most dangerous forms of radiation due to its ability to penetrate deeper into the body and cause damage to cells and DNA. However, the level of danger also depends on the dose and exposure time.
What is the most dangerous radiation and how can it be harmful to living organisms?
The most dangerous radiation is ionizing radiation, which includes gamma rays, X-rays, and some types of ultraviolet radiation. Ionizing radiation can harm living organisms by damaging cells and DNA, leading to mutations, cancer, and other health problems.
What makes one feel the heat of a candle?
radiation and convection and nerve cells in the skin
Which is the most dangerous type of nuclear radiation if the source is outside the body?
Gamma radiation is the most dangerous type of nuclear radiation if the source is outside the body, as it can penetrate through the body causing damage to cells and DNA. It has the highest energy and can travel the farthest distances.
Is it dangerous to be around radiation patients?
When sick people are treated with radiation, that does not make them radioactive. Radiation is dangerous, but radiation patients are not.
What radiation is dangerous to us?
Ionizing radiation, such as X-rays and gamma rays, is considered dangerous to humans as it can damage cells and DNA, leading to potential health effects such as cancer and radiation sickness. Non-ionizing radiation, such as visible light and radio waves, is generally not harmful in the levels typically encountered in everyday life.
Why was the nuclear bomb dangerous?
Nuclear bombs can be dangerous as during a atomic bomb explosions, it produces radiation. The effects of radiation could be that it can cause permanent damage to cells and can cause mutation. Along with this, it could cause severe burns to the skin.
Why is nuclear radiation dangerous to human being'S?
Nuclear radiation can cause genetic mutations in our DNA, which can cause cancers. If the genetic mutations occur in the germ cells, then our gametes (sperm and egg cells) could have genetic mutations that could be passed on to our offspring. Also, if radiation levels are high enough, people can get radiation sickness, which can be fatal.
