WebInertia is a property of matter that causes it to resist changes in velocity (speed and/or direction). According to Newton's first law of motion, an object with a given velocity maintains that velocity unless acted on by an external force. Inertia is the property of matter that makes this law hold true. WebReview ¾List the three methods of reducing your exposure/dose: ¾Intensity decreases _____ with the square of the distance from the source due only to the change in _____. H-117 – Introductory Health Physics Slide 31 ¾Using the inverse square law, calculate the dose rate at 4 feet away from a point source if the dose rate is originally 1000 R/hr at 2 feet. farm service agency greenwich ny

This activity gives an easy way for students to measure the WebApply the Inverse Square law to create safe distances, times, or radiation amounts. Inverse Square law: The radiation Intensity is inversely proportional to the square of the distance. Notice in the diagram that as the distance doubles, the area quadruples and thus, the initial radiation amount is spread over that entire area and is therefore ... free scrapbooking supplies by mail
