What radiation is used in hospitals and how does it cause a problem for staff/workers?

Answers

Answer 1

Answer: Radiation is used for X-rays, MRIS, any type of cancer killing.
Too much of radiation can be a dangerous thing... you could end up dying from a lot of exposure.

Answer 2

Answer: The radiation used is gamma radiation. It causes a problem for staff/workers as it's highly penetrating meaning it can penetrate (go through) almost anything . The staff/workers will have a lot of exposure to this gamma radiation and too much exposure allows the radiation to kill cells, even the useful ones.

What is the total of O2 + CO2

Answers

Answer:

The total of O2 + CO2 is not a mathematical expression that can be added together.

O2 and CO2 represent different chemical compounds: O2 refers to oxygen gas (two oxygen atoms bonded together), and CO2 refers to carbon dioxide (one carbon atom bonded to two oxygen atoms).

In chemistry, we do not add or combine the formulas of different compounds in the same way we add numbers. Instead, we use chemical reactions and equations to understand how elements and compounds interact and form new substances.

In the food chain below, which is the producer?
flower - mouse - snake- hawk

Answers

The question is asking us the following: "In the food chain below, which is the producer? And the food chain is: flower - mouse - snake- hawk", The producer is the organism that can produce energy from the source, typically from the sunlight, without eating parts of other animals. Producers are plants - and almost all plants are produces (some are also consumers). so the answer is "flower'

The producer is the flower.

Which of these is most likely to produce heavy metal waste? A. Leather tannery
B. Medical center
C. Paper mill
D. Oil refinery

Answers

Answer:

Option A, Leather tannery

Explanation:

In a leather industry, chromium is one of the heavy metals that are used in large amount.

Along with tannery, Chromium is also used in electroplating, and metallurgical industries.

The water coming out of these tannery has high content of chromium ion (Cr6+) generally ranging between 100–200 mg/L. This chromium rich water needs sufficient treatment before discharge or else it would cause bio magnification effect

Hence, option A is correct

C. A paper mill (APEX)

List three environmental factors that could cause certain neurological conditions and indicate the neurological disease caused by each one.I did this:
Three environmental factors that could cause certain neurologist conditions:
- Radiation: This may produce Cancer in the brain, making it spread.
- Genetic Mutation: This has many symptoms, it can cause autism, Down syndrome, strokes etc.)
- A lot of Drugs/Alcohol: This may cause long term diseases, delirium, and dementia.

Is it okay?

Answers

Answer:

Three environmental factors can be:

1.Ionizing radiation: cancer in the bone marrow or stomach

2.Solar radiation: skin cancer

3. Electromagnetic fields: induction of cataracts of the eyes.

Explanation:

1. Radiation sickness occurs when exposed to very high doses of ionizing radiation. It may be acute or chronic. The risk for cancer is dose dependent and an accumulation effect begins if the doses are very low.

2. Skin cancer is malignant that is caused by the uncontrolled division and growth of skin cells, with the ability to invade healthy tissues.

3. The thermal effects of electromagnetic fields produced by radar waves include the increase in body temperature by more than 1º C. Its effects include the cataracts of the eyes, and physiological and thermo-regulatory responses as the body temperature increases .

Maria is concerned because she has been exposed to a small amount of radiation during an X-ray. What is her doctor most likely to tell her?

Answers

The doctor should reassure the patient that exposure to radiation from a medical device becomes dangerous only if it is exposed for a long time, in high doses, or repeatedly.

It is true that there is a particular risk for pregnant women with regard to the fetus. In this case, the ratio between the benefit to the patient and the possible risk of side effects should always be taken into account.

Many people have been exposed to radiation- and that she shouldnt be worried because the amount of radiation she was exposed to was very little and most likely wont effect anything or anyone.
