Abstract

Personal radiation detection devices, methods of obtaining radiation exposure data, and networks of personal radiation devices. The detection devices may include passive devices and active devices. The passive detection devices may have the same form factor as credit cards or be included in common types of credit card form factor sized cards.

a body having a frontside and an opposing backside;

a window in said body, said window open to said frontside and said backside of said body; and

a radiation detection layer positioned in said window, said radiation detection layer comprising a material that will undergo a change in optical density, color, color intensity, electrical capacitance, electrical conductance or tensile strength upon exposure to ionizing radiation.

2. The device of claim 1, said body further including equal length opposing top and bottom edges and equal length opposing left and right side edges, no width, length or thickness dimension of said body being greater that a corresponding width, length or thickness dimension of a common credit card.

3. The device of claim 1, wherein said radiation detection layer comprises regions having sensitivities to different doses of a same type or types of ionizing radiation.

4. The device of claim 1, wherein said ionizing radiation comprises alpha radiation, beta radiation, gamma radiation, neutron radiation or combinations thereof.
