There are several different types of diabetes. Gestational diabetes begins during pregnancy and disappears following delivery. Another type of diabetes is referred to as type 1 diabetes (sometimes called juvenile diabetes or insulin-dependent diabetes). These individuals usually (although not always) develop their disease before age 20. People with type 1 diabetes must take insulin by injection every day. Approximately 10 percent of all people with diabetes have type 1.

There are several types of diabetes. The most common are type 1 and type 2. In type 1, the pancreas makes little or no insulin. Individuals with type 1 need insulin shots in order to stay alive. Type 1 can occur at any age, but is usually seen in children and young adults. With type 2 diabetes, the pancreas produces some insulin, but the amount is either not enough or is not effective, because the body's cells are resistant to it.

The following types of diabetes and some of their risk factors are quoted from the National Diabetes Fact Sheet: National estimates and general information on diabetes in the United States (Centers for Disease Control and Prevention. Atlanta, GA: US Department of Health and Human Services, 1997): Type 1 diabetes was previously called insulin-dependent diabetes mellitus (IDDM) or juvenile-onset diabetes. Type 1 diabetes may account for 5% to 10% of all diagnosed cases of diabetes.

Natural radiation takes the same forms as "human-caused" radiations. All the same decays discussed above happen naturally. Radiation we are exposed to from our environment include Cosmic (high energy particles and EM from outside of our galaxy), Cosmic induced (C-14, Tritium made in the atmosphere by interactions with cosmic radiation), Solar (UV from the sun mostly, but in space can be particles), and terrestrial (Uranium, Thorium, Radon contained in the Earth itself).

Yes. With multiple question types, twenty-five question formats—like select one, check all, and text—allow you to define how you ask the question and more importantly gather the question-related data. This enables you to leverage industry standards and your best practices to offer respondents ease-of-use and familiarity that can translate to increased response rates and better results.

Among Americans aged 20 years or younger, less than one-quarter of 1% (about 176,500 people) have diabetes. The prevalence of diabetes increases among older people. Among Americans aged 60 years or older, 20.9% (10.3 million people) have diabetes.
