Carbon dating is

  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
Reveal answer Fill a bubble to check yourself
A Correct answer
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.

i) Radio sodium a) Thyroid gland
ii) Radio phosphorus b) Cancer
iii) Radio cobalt circulation c) Blocks in blood
iv) Radio iodine d) Leukamia

  1. i-c, ii-b, iii-a, iv-d

  2. i-a, ii-c, iii-b,iv-d

  3. i-c, ii-d, iii-b, iv-a

  4. i-d, ii-b, iii-c, iv-a
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.

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.
