PROBLEM TO BE SOLVED: To provide a radiation dose measuring apparatus and a radiation dose measuring method for wheeled vehicles that can efficiently and accurately measure spatial doses of radiation around wheeled vehicles.SOLUTION: A radiation dose measuring apparatus is equipped with a pair of side spatial dose detecting devices 2 that are arranged along two sides of a vehicle stop area R of a wheeled vehicle 1 at halt in prescribed height positions and detect spatial doses on the two sides of the wheeled vehicle 1, and a front spatial dose detector 3 and a rear spatial dose detector 4 that are arranged along the front and rear sides of the vehicle stop area R of the wheeled vehicle 1 at halt to detect spatial doses in the front and rear parts of the wheeled vehicle 1. Further, the front spatial dose detector 3 and the rear spatial dose detector 4 are disposed to be able to move ahead or behind along with the forward or backward motion of the wheeled vehicle 1 relative to prescribed positions ahead of or behind the vehicle stop area R.SELECTED DRAWING: Figure 1 【課題】効率的且つ精度よく車両周囲の放射線の空間線量を測定できる車両の放射線量測定装置及び車両の放射線量測定方法を提供する。【解決手段】車両停車領域Ｒの両側部の所定の高さ位置に、停車した車両１の両側部に沿ってそれぞれ配設されて車両１の側方の空間線量を検出する一対の側部空間線量検出部２と、車両停車領域Ｒの前部と後部の所定の高さ位置に、停車した車両１の前部と後部に沿ってそれぞれ配設されて車両１の前方と後方の空間線量を検出する前部空間線量検出部３及び後部空間線量検出部４とを備える。また、前部空間線量検出部３と後部空間線量検出部４を、車両１の車両停車領域Ｒに対する進入／退出に応じ、車両停車領域Ｒの前部と後部の所定位置に対して進退可能に設ける。【選択図】図１
