Abstract
A visually readable nuclear radiation measurement device functioning as a dose rate meter or a dosimeter. There are disclosed several embodiments allowing the user to match the brightness of a scintillating means to a reference light source thereby to ascertain the desired dose rate radiation information and allowing the user to match the brightness of light penetrating a dye type dosimeter to a reference light source to ascertain the total dose.
Claims51
A method for measuring nuclear radiation comprising:
- providing means sensitive to nuclear radiation;
- providing a reference light source;
- while viewing the light from said source and said radiation sensitive means adjusting the light reaching the viewer's eye until the apparent brightness level of light from said source and said radiation sensitive means is substantially the same;
- and
- after adjusting the apparent brightness ascertaining quantitatively the level of nuclear radiation measured.
A method for measuring nuclear radiation comprising:
- providing means sensitive to nuclear radiation for providing visible light responsive to said radiation;
- providing a reference light source;
- while viewing the light emanating from each source thereof adjusting the light reaching the viewer's eye from one of said sources relative to the other until the brightness level of light from each of the sources is substantially the same;
- and
- after adjusting the apparent brightness ascertaining quantitatively the level of nuclear radiation measured.
Apparatus for measuring nuclear radiation comprising:
- housing means which is permeable to nuclear radiation;
- means sensitive to nuclear radiation mounted within said housing;
- a reference light source means mounted within said housing;
- viewing means carried by said housing for enabling a user of said apparatus to simultaneously view light from said reference and said radiation responsive means;
- means disposed within said housing for adjusting the apparent brightness level from said source and said radiation responsive means until the brightness levels appear substantially the same to the user;
- and
- means for providing a quantitative indication representative of the level of nuclear radiation measured.

- a reference light source means mounted within said housing;
- viewing means carried by said housing for enabling a user of said apparatus to simultaneously view light emanating from said reference and said radiation responsive means;
- means disposed between said viewing means and said sources of light for adjusting the brightness level from one of said sources relative to the other until a brightness level of light from each of said sources appears substantially the same to the user;
- and
- means for providing a quantitative indication representative of the level of nuclear radiation measured.
