Which statements accurately relate radiation and health? Check all that apply.

Ionizing radiation produces ions that disrupt natural chemical reactions in the body.
Stochastic effects are associated with short-term, high-level exposure to radiation.
Cancer and DNA mutations are examples of non-stochastic effects.
A single X-ray delivers about of the radiation exposure permitted for one person per year.
Lead shielding is an effective means of reducing radiation exposure.

Place several e-field sensors at a few points on different equipotential lines, and look at the relationship between the electric field and the equipotential lines. which statement is true? 1-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of higher voltages. 2-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of lower voltages. 3-at any point, the electric field is parallel to the equipotential line at that point.
