| Abstract | 「1. 緒言」ラジオアイソトープの医学的利用の健全な進歩を望むためには汚染物質の廃棄の問題は重要である. ことに体内投与をうけた患者の場合 尿等の排泄物を法律に決められた濃度以下にして下水道に放出するのは膨大な容量をもった貯留槽が必要であり, とくに131I-NaIによる治療を行なった場合は放射能量が大きいためにその容量が問題となり, したがって131I治療患者の入院を不可能あるいは制限せざるを得ないことが生じている. そこで我々はまず131I治療患者の尿の処理を主目的としてその処理方法について種々検討を加えた結果, 取扱が簡便で容易な装置を作成することができたのでここに報告する. 「2. 方法ならびに結果」患者尿から131Iを吸着し, 固形化する方法としては大きくわけて2つある. その第1は化学薬品による沈殿法である. まず硝酸銀を用いて沈殿を得る方法について検索したが, 沈殿に含まれる131I量が条件により異なり不安定であること, また操作が煩雑であること, 沈殿物の容量が多いこと, 高価であることなどから実用に供するのは適当でないとの結論となった. |

| Abstract | [Summary] It is well known that very large storage tanks for radioactive liquids are necessary for the disposal of wastes such as urine, serum, and water contaminated with radioactivity into a drainage system according to legal restrictions which require the radioactivity to be kept at certain low levels. Such tanks, however, are very expensive and also require much space. In order to combat this problem we designed a new apparatus for the disposal of the contaminated urine of patients with hyperthyroidism who have been treated with 131I-NaI. The apparatus has a lead shield box in which are placed two plastic cylinders containing ion exchange resin. The two cylinders are of the same shape and size and contain the same volume of resin. The first cylinder is connected to a siphon-like tube to the second cylinder and the second cylinder is connected by a siphon-like tube to the drainage pipe. The urine is thrown into the first cylinder through a funnel at the top of the shield box, and it flows into the drainage pipe after passing through the two cylinders. The radioactvei level of the urine thus disposed is lowered by less than one percent of original activity. This apparatus is small and portable and handles very easily. We are now in the process of attempting to make it more compact. |
