In radioactive Î± decay, a nucleus with Z protons and a total of A nucleons decays to a lower energy. state with (Z-2, A-4) by emission of an âÎ± particleâ, a tightly bound nuclear fragment comprising 2. protons and 2 neutrons.
Insurance underwriters must achieve a balance between risky and cautious decisions. If underwriters allow too much risk, the insurance company will pay out too many claims. But if they don't approve enough applications, the company will not make enough money from premiums. Most insurance underwriters specialize in one of three broad fields: life, health, and property and casualty.
In liability insurance claims, when two policies cover the same loss, one usually applies on a primary basis and the other on an excess basis. This means that one will pay first (the primary policy), and the other will pay only if the primary policy either does not cover the loss at all or if the amount of insurance is not enough to pay for the entire loss.
