Claim Text:
1. A hand-held alpha radiation detector comprising: a) an ionizing radiation detector comprising: wherein a circuit couples the first electrode with the second electrode and a resistor along said circuit produces a voltage that is a function of an amount of ionizing radiation within the ion chamber; b) an audible alert feature; wherein the audible alert emits a sound when an unsafe level of radiation is detected for an input selection selected on the hand-held-alpha radiation detector; and whereby the audible alert feature emits a sound having a frequency that corresponds to said voltage; c) a food products input selector; wherein said audible alert feature emits said sound when an unsafe level of alpha radiation is detected for food products; d) a radon gas input selector; wherein said audible alert feature emits said sound when an unsafe level of alpha radiation is detected for radon gas; wherein the hand-held alpha radiation detector is of a size that can be carried in a person's hand; wherein all dimensions of the hand-held alpha radiation detector including a length, a width, and a thickness are each no more than 20 cm wherein a baseline voltage is produced when the hand-held alpha radiation detector is turned on and held in an ambient environment.
