本発明は、濃度兼放射線量測定器に関する。 The present invention relates to a concentration and radiation dose measuring device.

近年の食品に対する安全性の意識の高まりから、食品に含まれる放射線量を一般人でも簡単に測定することができる種々の簡易型放射線測定器が提案されている（例えば、特許文献１参照）。 Due to the growing awareness of food safety in recent years, various simple radiation measuring instruments have been proposed that allow even ordinary people to easily measure the radiation dose contained in food (see, for example, Patent Document 1).

特開２０１３−１５２１２１号公報Japanese Unexamined Patent Publication No. 2013-152121

しかし、例えば、店舗で青果物を販売する時や、家庭で放射線を測定する時には、放射線量の他に糖度や塩分濃度等の濃度を合わせて測定したい場合もあり、濃度と放射線量を測定できる測定器が求められていた。 However, for example, when selling fruits and vegetables at a store or when measuring radiation at home, there are cases where it is desired to measure the concentration such as sugar content and salt concentration in addition to the radiation dose, and the concentration and radiation dose can be measured. A vessel was sought.

本発明はこのような事情を考慮してなされたもので、濃度と放射線量を容易に測定することができる濃度兼放射線量測定器を提供することを目的とする。 The present invention has been made in consideration of such circumstances, and an object of the present invention is to provide a concentration / radiation dose measuring device capable of easily measuring a concentration and a radiation dose.

本発明に係る濃度兼放射線量測定器は、上述した課題を解決するために、検出面と、前記検出面に載せられた試料の所定成分の濃度を測定する濃度センサと、前記検出面に載せられた試料の放射線量を測定する放射線センサと、を有する。 In order to solve the above-mentioned problems, the concentration / radiation dose measuring device according to the present invention has a detection surface, a concentration sensor for measuring the concentration of a predetermined component of a sample mounted on the detection surface, and a concentration sensor mounted on the detection surface. It has a radiation sensor that measures the radiation dose of the sample.

本発明に係る濃度兼放射線量測定器は、濃度と放射線量を容易に測定することができる。 The concentration and radiation dose measuring device according to the present invention can easily measure the concentration and the radiation dose.

本発明に係る濃度兼放射線量測定器の一実施形態を添付図面に基づいて説明する。 An embodiment of the concentration / radiation dose measuring device according to the present invention will be described with reference to the accompanying drawings.

図１は、本発明の実施形態に係る濃度兼放射線量測定器１の外観を示す説明図である。図２は、本発明の実施形態に係る濃度兼放射線量測定器１の機能ブロック図である。本実施形態に係る濃度兼放射線量測定器１は、検出面３と、糖度センサ１１と、放射線センサ１２と、操作部５と、を備える。 FIG. 1 is an explanatory view showing the appearance of the concentration / radiation dose measuring device 1 according to the embodiment of the present invention. FIG. 2 is a functional block diagram of the concentration / radiation dose measuring device 1 according to the embodiment of the present invention. The concentration / radiation dose measuring device 1 according to the present embodiment includes a detection surface 3, a sugar content sensor 11, a radiation sensor 12, and an operation unit 5.

検出面３は、糖度センサ１１を構成する部材であり、糖度を測定する試料が載せられる。検出面３としては、プリズムが用いられる。本実施形態における試料の状態は、特に限定されるものではなく、固体であってもよいし、液体であってもよい。また、本実施形態においては、破壊方式または非破壊方式のどちらを採用しても測定することができる。非破壊方式を採用する場合には、試料を細断（破壊）することなく、後述する放射線検出面４を試料に近づけることで放射線量を測定することができる。 The detection surface 3 is a member constituting the sugar content sensor 11, and a sample for measuring the sugar content is placed on the detection surface 3. A prism is used as the detection surface 3. The state of the sample in this embodiment is not particularly limited, and may be a solid or a liquid. Further, in the present embodiment, the measurement can be performed regardless of whether the destructive method or the non-destructive method is adopted. When the non-destructive method is adopted, the radiation dose can be measured by bringing the radiation detection surface 4 described later close to the sample without shredding (breaking) the sample.

糖度センサ１１は、本体２の内部に配置される。本実施形態において、糖度センサ１１は、試料が載せられた検出面３に向かって内部の光源から光を照射し、光の屈折率を測定することで、試料の所定成分の濃度を測定する、一般的な屈折計を用いることができる。 The sugar content sensor 11 is arranged inside the main body 2. In the present embodiment, the sugar content sensor 11 measures the concentration of a predetermined component of the sample by irradiating light from an internal light source toward the detection surface 3 on which the sample is placed and measuring the refractive index of the light. A general refractometer can be used.

放射線センサ１２は、本体２の内部に配置される。放射線センサ１２は、検出面３を底面として立ち上がる放射線検出面４を介して、検出面３に載せられた試料の放射線量を非接触で測定する。本実施形態では、放射線センサ１２として、ＧＭ計数管式サーベイメーター、ＮａＩ（ＴＩ）シンチレーション式サーベイメーター、Ｓｉ（Ｌｉ）半導体検出器、またはＧｅ半導体検出器等を用いることができる。 The radiation sensor 12 is arranged inside the main body 2. The radiation sensor 12 measures the radiation dose of the sample placed on the detection surface 3 in a non-contact manner via the radiation detection surface 4 that rises with the detection surface 3 as the bottom surface. In the present embodiment, as the radiation sensor 12, a GM counter tube type survey meter, a NaI (TI) scintillation type survey meter, a Si (Li) semiconductor detector, a Ge semiconductor detector, or the like can be used.

放射線センサ１２を本体２の内部に配置する場合には、試料に含まれる放射線を本体２の内部に導きやすくするために、放射線検出面４に吸気口を設ける構成としてもよい。この場合、液体試料の測定を考慮して、放射線検出面４に防水性の繊維シート（放射線や空気を透過させ、液体を遮断するもの）等を貼り付け、本体２内部への試料の侵入を妨げることが好ましい。 When the radiation sensor 12 is arranged inside the main body 2, an intake port may be provided on the radiation detection surface 4 in order to easily guide the radiation contained in the sample to the inside of the main body 2. In this case, in consideration of the measurement of the liquid sample, a waterproof fiber sheet (which allows radiation and air to pass through and blocks the liquid) or the like is attached to the radiation detection surface 4 to prevent the sample from entering the main body 2. It is preferable to prevent it.

また、放射線センサ１２は、放射線検出面４に配置される構成としてもよい。この場合、放射線検出面４は、放射線を検知する部材から形成される。そして、本体２の内部には、放射線検出面４で検知した放射線を測定する電子回路が設けられる。 Further, the radiation sensor 12 may be configured to be arranged on the radiation detection surface 4. In this case, the radiation detection surface 4 is formed of a member that detects radiation. Then, an electronic circuit for measuring the radiation detected by the radiation detecting surface 4 is provided inside the main body 2.

本実施形態においては、放射線量を測定する手段として、放射線検出器外部器７をさらに備えてもよい。これにより、放射線検出器外部器７を試料に近づけることにより放射線量の測定が可能となる。 In the present embodiment, a radiation detector external device 7 may be further provided as a means for measuring the radiation dose. As a result, the radiation dose can be measured by bringing the radiation detector external device 7 closer to the sample.

操作部５は、濃度の測定、放射線量の測定、および濃度の測定と放射線量の測定から構成される測定種別を切り替える入力を受け付ける。測定種別は、糖度の測定、放射線量の測定、全測定（糖度および放射線量の測定）である。図１において操作部５は、本体の表面に設けられたスイッチである。本体表面に記載された測定種別にスイッチを合わせると、測定種別を切り替える入力が受け付けられる。操作部５の形態は特に限定されるものではなく、例えば、ボタンであってもよい。操作部５により、測定種別を全測定に設定すると、糖度と、放射線量とが同時に測定される。 The operation unit 5 receives an input for switching a measurement type consisting of a concentration measurement, a radiation dose measurement, and a concentration measurement and a radiation dose measurement. The measurement types are sugar content measurement, radiation dose measurement, and total measurement (sugar content and radiation dose measurement). In FIG. 1, the operation unit 5 is a switch provided on the surface of the main body. When the switch is set to the measurement type written on the surface of the main body, the input to switch the measurement type is accepted. The form of the operation unit 5 is not particularly limited, and may be, for example, a button. When the measurement type is set to all measurements by the operation unit 5, the sugar content and the radiation dose are measured at the same time.

表示部６は、測定された糖度または放射線量を表示する。切替部１３は、測定種別の切替えを制御し、操作部５により選択された測定種別に応じて糖度センサ１１または放射線センサ１２を作動させる。 The display unit 6 displays the measured sugar content or radiation dose. The switching unit 13 controls switching of the measurement type, and operates the sugar content sensor 11 or the radiation sensor 12 according to the measurement type selected by the operation unit 5.

以下、濃度兼放射線量測定器の作用について説明する。 Hereinafter, the operation of the concentration / radiation dose measuring device will be described.

試料を検出面３に載置し、操作部５を所望の測定種別に合わせる。糖度の測定が選択された場合には、切替部１３により制御され、糖度センサ１１が動作する。糖度センサ１１により試料の所定成分の糖度が測定され、測定値は表示部６に表示される。放射線量の測定が選択された場合には、切替部１３により制御され、放射線センサ１２により試料の放射線量が測定され、測定値は表示部６に表示される。また、全測定が選択された場合には、糖度センサ１１および放射線センサ１２による測定が同時に行われ、測定値は表示部６に表示される。 The sample is placed on the detection surface 3 and the operation unit 5 is adjusted to the desired measurement type. When the measurement of the sugar content is selected, the sugar content sensor 11 operates under the control of the switching unit 13. The sugar content sensor 11 measures the sugar content of a predetermined component of the sample, and the measured value is displayed on the display unit 6. When the measurement of the radiation dose is selected, it is controlled by the switching unit 13, the radiation dose of the sample is measured by the radiation sensor 12, and the measured value is displayed on the display unit 6. When all the measurements are selected, the sugar content sensor 11 and the radiation sensor 12 perform the measurements at the same time, and the measured values are displayed on the display unit 6.

このような本発明に係る濃度兼放射線量測定器は、糖度と放射線量を容易に測定することが可能であり、また、糖度と放射線量を同時に測定することもできる。 Such a concentration / radiation dose measuring device according to the present invention can easily measure the sugar content and the radiation dose, and can also measure the sugar content and the radiation dose at the same time.

本発明の濃度兼放射線量測定器は上記実施形態に限定されず、本発明の主旨を逸脱しない範囲において、種々の改良や変更を行うことができる。例えば、糖度以外でも塩分濃度、酸度等、種々の成分濃度を計測してもよい。また、２つ以上の成分濃度と放射線量を計測可能に構成してもよい。 The concentration / radiation dose measuring device of the present invention is not limited to the above embodiment, and various improvements and changes can be made without departing from the gist of the present invention. For example, other than sugar content, various component concentrations such as salinity and acidity may be measured. Further, it may be configured so that the concentration of two or more components and the radiation dose can be measured.
