  1. a process to determine the age of archaeological samples

  2. a medicine for treatment of cancer

  3. a process to determine the age of a meteorite

  4. a process of treatment of diseases in animals

Show answer
Correct Option: A
Explanation:
Carbon dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon (${}^{14}C$), a radioactive isotope of carbon.

__________ arises from the 'burning' of uranium fuel in a nuclear reactor. 

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

  1. Low-level- waste

  2. High-level waste

  3. Intermediate level waste

  4. Very low level waste

Show answer
Correct Option: B
Explanation:

High level waste 

High level radioactive waste are highly radioactive materials produced as a by product of the nuclear reactions that occurs inside the nuclear reactor. 

The degree and kind of damage due to radiation varies in which of the following ways?

  1. kind of radiation

  2. duration of exposure

  3. amount of radiation

  4. All of the above

Show answer
Correct Option: D
Explanation:

All of the above 

The degree of damage due to radiation depends on kind of radiation, duration of exposure and amount of radiation.

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.

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.
