Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Thyroid disease is cured using - Radio Iodine
Cancer - Radioactive Cobalt circulation (Chemo)
Blocks in blood - Radio Sodium
Leukemia - Radio Phosphorus
Hence option C is correct.

Fill in the blank.

Radioactive contamination can enter the body through ____________.

  1. inhalation

  2. ingestion

  3. absorption

  4. all of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

D

Radioactive contamination can enter into the body through inhalation, ingestion and absorption. It causes serious biological effects to our body. Radioactive waves are capable to enter the body directly through penetration. It can also be inhaled or ingested. 

Multiple choice chemistry nuclear physics hazards and safety measures of radiations harmful effects and safety precautions for radiations energy production

Spent fuel rods and obsolete nuclear weapons are examples of 

  1. decommissioned waste

  2. high-level nuclear waste

  3. low-level nuclear waste

  4. recycled nuclear waste

  5. itinerant nuclear waste
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

High level nuclear waste 

High level radioactive waste are the highly radioactive materials that produced as a byproduct of the reactions that occur inside nuclear reactor. Spent fuel and obsolete nuclear weapons are example of high lever nuclear waste. 

Multiple choice physics nuclear physics hazards and safety measures of radiations harmful effects and safety precautions for radiations energy production

The rad is the correct unit used to report the measurement of 

  1. the rate of decay of radioactive source

  2. the ability of a beam of gamma ray photons to produce ions in a target

  3. the energy delivered by radiation to a target.

  4. the biological effect of radiation
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Rad is the unit of absorbed dose of ionizing radiation. One rad is equal approximately to the absorbed dose delivered when soft tissue is exposed to one-roentgen of medium-voltage radiation.  Thus this is the bilogical effect of radiation.

Radiation exposure comes from

  1. Background Sources

  2. Manmade sources

  3. Medical processes

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Because of Man made processes , there will be radiation exposure. For example we can take bricks , it causes radiation

Because of Medical processes , we will get several radiation exposures . For example X ray radiation etc
Background sources also causes radiation
Therefore option $D$ is correct
