What type of water pollution can cause genetic mutations miscarriages, birth defects, and certain kinds of cancers?
A: Explosives
B: Sediment
C: Radiative material
D: Thermal
Radiative material can cause genetic mutations miscarriages, birth defects, and certain kinds of cancers. So, the correct option is (C).
What are Radiative materials?Radionuclides also called radioactive materials are defined as the class of chemicals where the nucleus of an atom is unstable which achieves stability through changes in the nucleus such as spontaneous fission, emission of alpha particles, or protonation of neutrons or reverse conversion.
Some examples are uranium and thorium, two radioactive elements that occur naturally in the Earth's crust. Over billions of years, these two elements slowly change forms and produce decay products such as radium and radon. These materials can cause cancer, genetic defects etc.
Radioactive Materials Radiation can damage the DNA in our cells where high doses of radiation can cause acute radiation syndrome (ARS) or cutaneous radiation injury (CRI). High doses of radiation can cause cancer in later life.
Thus, Radiative material can cause genetic mutations miscarriages, birth defects, and certain kinds of cancers. So, the correct option is (C).
