Control of exposure to radiation is driven by 3 factors- time, distance, and shielding. Radiation is subject to the "inverse square law- doubling distance reduces exposure by the inverse square- so a little distance (long handled tongs) reduces exposure a LOT.
In tongs, the fulcrum is the hinge point where the two arms of the tongs meet. The load is the object being picked up by the tongs, and the effort is the force applied by the user's hand to close the tongs around the object.
Dissipation - the heat energy that is transferred to the tongs is dissipated from the tongs to the surrounding area in order for the temperature of the whole system to be at an equilibrium.
Sugar tongs are an example of a class 2 lever. In this type of lever, the load is between the fulcrum and the effort.

Sodium is a highly reactive metal that can react violently with air and water, forming dangerous compounds and releasing flammable hydrogen gas. Handling sodium with tongs minimizes the risk of accidental contact with moisture or air, reducing the chance of a chemical reaction and potential hazards.
