What are the factors that affect the rate of radiation?

Finally this study found the need to be able to generalize these findings through an in-depth research on the factors affecting the external radiation dose rate, which includes radiopharmaceutical dose, urination frequency, the amount of water intake, fasting time and the use of contrast medium.

What are the three causes of radioactivity?

What causes atoms to be radioactive? Atoms found in nature are either stable or unstable. An atom is stable if the forces among the particles that makeup the nucleus are balanced. An atom is unstable (radioactive) if these forces are unbalanced; if the nucleus has an excess of internal energy.

Is radioactivity affected by external factors?

Their conclusion was that the decay rate was entirely independent of temperature. Since then, numerous investigations have shown that alpha and beta decays are not influenced by external conditions such as temperature, air pressure, or the surrounding material.

What four factors does the damage due to radiation exposure depend on?

The amount of damage that exposure to radiation can cause depends on several factors, including:

• The type of radiation.
• The dose (amount) of radiation.
• How you were exposed, such as through skin contact, swallowing or breathing it in, or having rays pass through your body.

What affects the half-life of a radioactive element?

Since the chemical bonding between atoms involves the deformation of atomic electron wavefunctions, the radioactive half-life of an atom can depend on how it is bonded to other atoms. Simply by changing the neighboring atoms that are bonded to a radioactive isotope, we can change its half-life.

What are the factors affecting nuclear stability?

The two main factors that determine nuclear stability are the neutron/proton ratio and the total number of nucleons in the nucleus.

What are the 3 types of radioactivity?

The three most common types of radiation are alpha particles, beta particles, and gamma rays.

How does radiation affect the environment?

Similarly to humans and animals, plants and soil are also affected negatively from high amounts of nuclear radiation. Just like in humans, radioactive material can damage plant tissue as well as inhibit plant growth. Mutations are also possible due to the damage caused to the DNA.

What are some harmful effects of radiation on humans and the environment?

Exposure to very high levels of radiation, such as being close to an atomic blast, can cause acute health effects such as skin burns and acute radiation syndrome (“radiation sickness”). It can also result in long-term health effects such as cancer and cardiovascular disease.

What are the health effects of radiation?

Health Effects of Radiation: Health Effects Depend on the Dose. We receive low doses of radiation from our natural environment. However, we know that radiation at high doses can be lethal. We know that radiation can cause cancer, and we also know radiation can be harmful to the fetus at various stages of pregnancy.

Why are some people more vulnerable to radiation exposure?

Infants, children, the elderly, pregnant women, and people with compromised immune systems are more vulnerable to health effects than healthy adults. The risk from radiation is higher for younger people mainly because: Also, some people within the same age group may have different sensitivity to radiation.

How can the radioactivity of a material be changed?

The radioactivity of a material does not depend on any external conditions, except for two items. Other than the two exceptions, there is nothing that be done to change the half-life or radioactivity of something.

Does radiation cause hereditary effects?

And, although we haven’t seen it in humans, radiation can cause hereditary effects in lab animals. This is known as the dose rate. If a person receives a dose over an extended period of time, the impact on health won’t be as severe as if the same dose were received all at once.
