Abstract

The invention generally relates to a radiation shielding apparatus that includes a shielding box unit into which a radiation generating device is inserted, a locking unit disposed on an outside of the shielding box unit, an operation display unit disposed on the outside of the shielding box unit to display a locked state of the locking unit, and a control unit for controlling an operation of each of the radiation generating device and the operation display unit.

First claim

What is claimed is:

1. A radiation shielding apparatus comprising:
a shielding box unit into which a radiation generating device is inserted;
a locking unit disposed on an outside of the shielding box unit;
an operation display unit disposed on the outside of the shielding box unit to display a locked state of the locking unit; and
a control unit for controlling an operation of each of the radiation generating device and the operation display unit,
wherein, the shielding box unit comprises
(a) a cover,
(b) a shielding box locked with the cover by the locking unit and having a sidewall and a bottom surface,
(c) a sample holder therein,
(d) a through-hole defined in one side of the sidewall to allow a line to pass therethrough,
(e) a line guiding unit disposed in front of the through-hole and having a first plate and a second plate, each of which is manufactured with two layers in which lead is added on the inside of an aluminum plate, at a front side of the through-hole, and
(f) the first plate is bent so that a bent portion of the first plate is disposed in front of the through-hole and the second plate is bent so that a bent portion of the second plate is disposed in front of the through-hole, and
(g) the bent portion of the first plate and the bent portion of the second plate are disposed in parallel and spaced a predetermined distance apart from each other, thereby preventing the radiation from leaking through the through-hole.

2. The radiation shielding apparatus of claim 1 , wherein the shielding box further comprises a vibration detection sensor connected to the control unit and disposed on an outside of a front sidewall thereof to detect vibration.

3. The radiation shielding apparatus of claim 1 , wherein the shielding box further comprises a radiation detection sensor connected to the control unit and disposed therein to detect radiation.

4. The radiation shielding apparatus of claim 1 , wherein the locking unit comprises:
a cover locking part disposed on an outer surface of the cover; and
a locking detection part disposed on the shielding box unit to detect the locked state of the shielding box unit when the shielding box is locked with the cover by the cover locking part.

5. The radiation shielding apparatus of claim 4 , wherein the locking detection part comprises:
a push part disposed on the cover; and
an interlock disposed on the shielding box to correspond to the push part to detect the push part, thereby outputting a locking detection signal.

6. The radiation shielding apparatus of claim 4 , wherein the cover locking part comprises:
a hook disposed on the cover; and
a buckle coupled to the hook and disposed to correspond to the hook of the shielding box.
