1.	Factors that reduce the dose to the patient include: a. Increased filtration b. Reduced collimation c. Using a grid with paediatric patients d. Using an intensifying screen e. Increasing the X-ray focus-to-patient distance
Answer» a. True. b. False. Better collimation prevents unnecessary exposure to tissues and also acts to reduce scatter. c. False. As younger patients are smaller, a lower kV may be used and so scatter will be less and grids can be avoided. Because grids reduce the intensity of the main radiation beam, a grid will result in an increased dose to the patient by increasing the required mA. d. True. e. True. However, this can lead to a reduction in magnification.

How do biofertilisers enrich the fertility of the soil?
Read carefully the passage and select the correct answer out of given four options:Biofertilizers are organisms that enrich nutrient quality of the soil. The important sources of biofertilizers are bacteria, fungi and cyanobacteria. The symbiotic association of Rhizobium with the root nodules of leguminous plants is the common example.
