Walter E. Fernald Developmental Center

Walter E. Fernald giteza imbere, nicyo kigo cya kera cy’iburengerazuba bw’ibigo byatewe inkunga na leta bikorera ababana n'ubumuga bwiterambere .   Ku buyobozi bwa gatatu, Walter Fernald, byabaye icyitegererezo ku bigo bya Leta ku bamugaye mu iterambere. Nyuma niho habaye ubushakashatsi bwubuvuzi mu kinyejana cya 20. Iperereza kuri ubu bushakashatsi ryatumye amabwiriza mashya yerekeye ubushakashatsi bwabantu mu bana.

Ishuri rifite  umutungo uri kumuhanda wa Trapelo muri Waltham, Massachusetts .

 Amateka 
Ikigo cya Fernald, ubusanzwe cyiswe Ishuri Rikuru ryigisha kwigisha no guhugura abana ba Idiotic,   ryashinzwe i Boston n’umuvugurura Samuel Gridley Howe mu 1848 hamwe n’amadolari 2,500 yatanzwe n’inteko ishinga amategeko ya Massachusetts . Ishuri ryagiye buhoro buhoro ryimukira ahitwa Waltham hagati ya 1888 na 1891. Amaherezo ryarimo inyubako 72 kuri    . Igihe cyo hejuru, ishuri ryafunze abantu bagera ku 2500, abenshi muri bo bakaba ari "abahungu batagira ubwenge ".

 Ubushakashatsi bwubuvuzi bwa kirimbuzi mubana 
Ishuri rya Fernald niryo ryakorewe ubushakashatsi bwakozwe na 1946–53 bwakozwe na kaminuza ya Harvard na MIT bwerekanaga abana bato b'abahungu kwanduza dosiye ya isotopi ya radio .  Inyandiko zabonetse mu 1994 n’ishami ry’ingufu muri Amerika  zagaragaje ibisobanuro bikurikira:

 Ubushakashatsi bwakozwe igice na mugenzi wawe wubushakashatsi yatewe inkunga na Quaker Oats Company . Bimwe mubushakashatsi bwarimo kongeramo ibyuma bya radio na calcium muri oatmeal n'amata, hanyuma kugaburira imvange kubanyeshuri ba Fernald. 
 MIT Porofeseri w’imirire Robert S. Harris yayoboye ubwo bushakashatsi, bwiga ku kwinjiza calcium na fer .
 Abahungu bashishikarijwe kwinjira muri "Science Club", yatangaga ibice byinshi byibiribwa, ibirori, ningendo zerekeza mumikino ya baseball ya Boston Red Sox .
 Abanyamuryango ba club 57 bariye ibinyampeke bikungahaye kuri fer hamwe namata ya calcium -akungahaye kumaseke ya mugitondo. Kugirango ukurikirane iyinjizwa, traseri nyinshi za radioaktiw za calcium zahawe umunwa cyangwa imitsi.
 Urwego rw'imishwarara mu ntebe no mu maraso byakora nk'ibihinduka biterwa.
 Mu bundi bushakashatsi, amasomo 17 yakiriye amafoto yinyongera arimo radioisotopi yicyuma. 
 Yaba abana cyangwa ababyeyi babo ntabwo bigeze batanga uburenganzira buhagije bwo kwitabira ubushakashatsi bwa siyansi.
