Nature Of Business Organization and Going Concern Disclosure [Text Block] | 1. NATURE OF BUSINESS, ORGANIZATION AND GOING CONCERN Cellectar Biosciences, Inc. (the “Company”) is a biopharmaceutical company developing compounds for the treatment, diagnosis and imaging of cancer. The Company’s headquarters are located in Madison, Wisconsin. The Company is subject to a number of risks similar to those of other small pharmaceutical companies. Principal among these risks are dependence on key individuals, competition from substitute products and larger companies, the successful development and marketing of its products in a highly regulated environment and the need to obtain additional financing necessary to fund future operations. The accompanying financial statements have been prepared on a basis that assumes the Company will continue as a going concern and that contemplates the continuity of operations, realization of assets and the satisfaction of liabilities and commitments in the normal course of business. The Company has devoted substantially all of its efforts toward research and development and has, during the six months ended June 30, 2016, generated an operating loss of approximately $ 4,334,000 The accompanying condensed consolidated balance sheet as of December 31, 2015 has been derived from audited financial statements. The accompanying unaudited condensed consolidated balance sheet as of June 30, 2016, the condensed consolidated statements of operations for the three months and six months ended June 30, 2016 and 2015, the condensed consolidated statements of cash flows for the six months ended June 30, 2016 and 2015 and the related interim information contained within the notes to the condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions, rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial information. Accordingly, they do not include all of the information and the notes required by U.S. GAAP for complete financial statements. In the opinion of management, the unaudited interim condensed consolidated financial statements reflect all adjustments which are of a nature necessary for the fair presentation of the Company’s consolidated financial position at June 30, 2016 and consolidated results of its operations for the three months and six months ended June 30, 2016 and 2015, and its cash flows for the six months ended June 30, 2016 and 2015. The results for the six months ended June 30, 2016 are not necessarily indicative of future results. These unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and related notes thereto included in the Company’s Form 10-K/A for the fiscal year ended December 31, 2015, which was filed with the SEC on March 11, 2016, as amended on July 18, 2016. 55,000 Lived Assets Equity.

Fair Value Disclosures [Abstract] | |
Fair Value Disclosures [Text Block] | 2. FAIR VALUE In accordance with the Fair Value Measurements and Disclosures Topic of the FASB ASC 820, the Company groups its financial assets and financial liabilities generally measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. · Level 1: Input prices quoted in an active market for identical financial assets or liabilities. · Level 2: Inputs other than prices quoted in Level 1, such as prices quoted for similar financial assets and liabilities in active markets, prices for identical assets and liabilities in markets that are not active or other inputs that are observable or can be corroborated by observable market data. · Level 3: Input prices quoted that are significant to the fair value of the financial assets or liabilities which are not observable or supported by an active market. To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level 3. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. The Company issued warrants to purchase an aggregate of 82,500 27,500 16,250 38,750 In August 2014, as part of an underwritten public offering, the Company issued 494,315 The Series A Warrants issued on October 1, 2015 were previously considered financial instruments; however, they were amended on April 20, 2016 in such a manner that they no longer contain a price protection clause, which was the characteristic that had initially resulted in their being accounted for as financial instruments. As a result, they are no longer classified as financial instruments, and have been reclassified to equity; therefore, they have been removed from the table below for the period ended June 30, 2016. The Series B Warrants issued on October 1, 2015 were all exercised by the holders during the three months ended June 30, 2016; therefore, they have been reclassified to equity and removed from financial instruments table presented below as of June 30, 2016 (see Note 3).

The future financing estimates are based on the Company’s estimates of anticipated cash requirements over the term of the warrants as well as the frequency of required financings based on its assessment of its historical financing trends and anticipated future events. Due to the nature of these inputs and the valuation technique utilized, these warrants are classified within the Level 3 hierarchy.

The future financing estimates were based on the Company’s estimates of anticipated cash requirements over the term of the warrants as well as the frequency of required financings based on its assessment of its historical financing trends and anticipated future events.

The Series A Warrants cover, in the aggregate, 150,003 28.30 3,300,000 2,868,000 3,750 28.30 61,000 In connection with the entry into the purchase agreement, the Company and the purchasers entered into a registration rights agreement, which required the Company to file a registration statement to provide for the resale of the shares of Common Stock issuable upon the exercise of the Series A Warrants. The Company will also be required to file one or more registration statements from time to time to register the issuance or resale of any additional shares of Common Stock that may become issuable as a result of the Offerings. The Company will be obligated to use its commercially reasonable efforts to keep any registration statement effective until the earlier of (i) the date on which the shares of Common Stock subject to the registration statement may be sold without registration pursuant to Rule 144 under the Securities Act, or (ii) the date on which all of the shares of Common Stock subject to the registration statement have been sold under the registration statement or pursuant to Rule 144 under the Securities Act or any other rule of similar effect. Warrant Restructuring On April 13, 2016, the Company entered into an exchange and amendment agreement (the “Warrant Restructuring Agreement”) pursuant to which the Company agreed to exchange the 2015 Pre-Funded Warrants relating to 48,274 1,062,000 Pursuant to the Warrant Restructuring Agreement, the Company also agreed with the holders of 2015 Series A Warrants that upon the consummation of the 2016 Underwritten Offering, the exercise price of the 2015 Series A Warrants would be reduced to the public offering price per share of the shares of common stock sold in this offering and that the warrants would be amended such that the exercise price would no longer be subject to adjustment in connection with future equity offerings we may undertake. On April 20, 2016, the Company issued to each of those holders, pursuant to the amendment, a new warrant to purchase 300,006 2.13 As a result of the amendment to the 2015 Series A Warrant agreement eliminating any future price adjustment potential in the 2015 Series A Warrants, and the settlement of the 2015 Series B Warrants due to their having been exercised, the fair value of these warrants on the date of amendment or settlement, respectively, has been reclassified to equity. Registration Rights In connection with securities purchase agreements the Company is required to keep the related registration statements continuously effective under the Securities Act of 1933, as amended (the “Securities Act”), until the earlier of the date when all the registrable securities covered by the registration statement have been sold or such time as all the registrable securities covered by the registration statement can be sold under Rule 144 without any volume limitations. The Company will be allowed to suspend the use of the registration statement for not more than 30 consecutive days on not more than two occasions in any 12-month period (the “Allowed Delay”). If the Company suspends the use of the registration for longer than the Allowed Delay, it may be required to pay to the purchasers liquidated damages equal to 1.5 5 Additionally, in connection with registered offerings of common stock and warrants the Company has entered into certain securities purchase agreements which require the Company to use commercially reasonable efforts to keep the applicable registration statements effective for the issuance of shares of common stock pursuant to the exercise of warrants issued in the offering as long as the warrants remain outstanding.

Income Tax Disclosure [Abstract] | |
Income Tax Disclosure [Text Block] | 6. INCOME TAXES The Company accounts for income taxes in accordance with the liability method of accounting. Deferred tax assets or liabilities are computed based on the difference between the financial statement and income tax basis of assets and liabilities, and net operating loss carryforwards (NOLs), using the enacted tax rates. Deferred income tax expense or benefit is based on changes in the asset or liability from period to period. The Company did not record a provision or benefit for federal, state or foreign income taxes for the six months ended June 30, 2016 or 2015 because the Company has experienced losses on a tax basis since inception. Because of the limited operating history, continuing losses and uncertainty associated with the utilization of the NOLs in the future, management has provided a full allowance against the value of its gross deferred tax asset. The Company also accounts for the uncertainty in income taxes related to the recognition and measurement of a tax position taken or expected to be taken in an income tax return. The Company follows the applicable accounting guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition related to the uncertainty in income tax positions. No uncertain tax positions have been identified. |

Earnings Per Share [Abstract] | |
Earnings Per Share [Text Block] | 7. NET LOSS PER SHARE Basic net loss per share is computed by dividing net loss by the weighted average number of shares of common stock outstanding during the period, including warrants that are exercisable for little or no additional consideration. Diluted net loss per share is computed by dividing net loss, by the sum of the weighted average number of shares of common stock and the dilutive potential common stock equivalents then outstanding. Potential common stock equivalents consist of stock options and warrants. Since there is a net loss attributable to common stockholders for the three months and six months ended June 30, 2016 and 2015, the inclusion of common stock equivalents in the computation for those periods would be antidilutive. Accordingly, basic and diluted net loss per share is the same for all periods presented. Six Months Ended June 30, 2016 2015 Warrants 4,629,842 660,409 Stock options 397,882 89,511 |

Stockholders' Equity, Reverse Stock Split | 1-for-10 reverse split | At a special meeting held on February 8, 2016, the Companys stockholders approved an amendment to the Companys certificate of incorporation to effect a reverse split of the Companys common stock at a ratio between 1:5 to 1:10 in order to ensure that adequate authorized but unissued shares would be available for anticipated future financings, and to satisfy requirements for the continued listing of the Companys common stock on the NASDAQ Capital Market. In addition, the proposal approved by the stockholders provided that if the reverse split was effected, the number of shares of common stock that the Company is authorized to issue remained unchanged at 40,000,000. The Companys stockholders further authorized the board of directors to determine the ratio at which the reverse split would be effected by filing an appropriate amendment to the Companys certificate of incorporation. The board of directors authorized the ratio of the reverse split and corresponding reduction in authorized shares on February 24, 2016, and effective at the close of business on March 4, 2016, the Companys certificate of incorporation was amended to effect a 1-for-10 reverse split of the Companys common stock (the 2016 Reverse Split). All share and per share numbers included in these consolidated financial statements give effect to the 2016 Reverse Split. | ||||||
