Fill in the blank.

Radioactive contamination can enter the body through ____________.

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

  1. inhalation

  2. ingestion

  3. absorption 

  4. all of the above

Show answer
Correct Option: D
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. 

Spent fuel rods and obsolete nuclear weapons are examples of 

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

  1. decommissioned waste

  2. high-level nuclear waste

  3. low-level nuclear waste

  4. recycled nuclear waste

  5. itinerant nuclear waste

Show answer
Correct Option: B
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. 

Which type of bag is general waste put into?

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

  1. Containers lined with black bags

  2. Containers lined with clear bags

  3. Sharp containers

  4. Containers lined with yellow bags

Show answer
Correct Option: A
Explanation:

Containers lined with black bags 

A typical black bin bag used for general waste. 

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

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

  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

Show answer
Correct Option: D
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

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

  1. Background Sources

  2. Manmade sources

  3. Medical processes

  4. All of the above

Show answer
Correct Option: D
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
