Chapter 7, Problem 4R
Summary Introduction
To review:
Effects of gamma radiation and UV radiation on microorganisms.
Introduction:
Antimicrobial is an agent that kills and stops the growth of microorganisms. Gamma radiation is an ionizing radiation with shorter wave length having the ability to penetrate deeply. UV radiation is a non-ionizing radiation with longer wave length having minimum ability to penetrate.

Hello,
Can you help me with a brief overview of the advantages and disadvantages of using "radiation" in a healthcare setting as a physical method to control microbial growth. (I would apreciate a short explanation).
Thank you in advance!
Which of the following is not a property of an antimicrobialagent?(a) Must have a favorable chemotherapeutic index(b) Must be selectively toxic(c) Must be effective against viral diseases(d) Must have a known concentration over a period oftime required to eliminate a pathogen(e) b and c
Could an organism that is susceptible to an antimicrobial agent in laboratory testing fail to respond to it when that drug is used to treat the patient? Explain.

They grew bacterial colonies of Salmonella typhimurium in petri dishes labelled A, B and C. The Petri dishes were kept at 36°C for 48 hours, with scientists observing the bacteria every 24 hours. The results for this investigation are below. Petri dish A B с Treatment Was subjected to ionising radiation followed immediately by a dose of antibiotic X An equal amount of antibiotic X was added (as was added to Petri dish A) Was given neither ionising radiation nor antibiotic X After 24 hours Small spots of growth on surface No growth Growth across whole surface After 48 hours (ii) Identify the purpose of petri dish C.
