Ultraviolet radiation is a chemical means of controlling microbial growth. Hence the correct option is d.
Ultraviolet (UV) radiation serves as a potent chemical agent for controlling microbial growth due to its ability to interfere with the genetic material of microorganisms. The high-energy UV rays cause damage to the DNA structure, inducing mutations and impairing the microorganisms' ability to proliferate. This method is particularly effective in disinfection processes, ensuring a broad and thorough microbial control. It finds applications in water treatment, air purification, and sterilization, making UV radiation a versatile and reliable tool in various industries for maintaining sanitary conditions.
In healthcare facilities, UV radiation is utilized for the disinfection of surfaces, air, and water, contributing to the prevention of hospital-acquired infections. Similarly, in the food industry, UV technology helps maintain product safety by controlling pathogens in liquids and on surfaces. The versatility and efficiency of UV radiation make it a valuable tool in the ongoing efforts to ensure public health and safety across various sectors. Hence the correct option is d.
